For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0035] When testing anti-UAV equipment, usually only a single module in the anti-UAV equipment can be tested, and it is difficult to determine whether the link function of the equipment at the system level is normal. If the conventional detection method is used to detect the anti-UAV equipment, it is necessary to perform a far-field effective isotropic radiated power (EIRP) test on the equipment in a darkroom to detect whether the function of the anti-UAV equipment is normal. However, this method has great limitations, such as the need to rely on a darkroom for detection, and the far-field test requirements are high, which cannot meet the real-time detection needs of field work or demonstrations. Therefore, there is currently a lack of a test system to achieve simple and effective system-level detection of the functions of anti-UAV equipment.

[0036] Based on the above considerations, the present application proposes an anti-UAV equipment testing system for detecting anti-UAV equipment, the testing system comprising a signal transceiver converter, a signal generating device and a controller, wherein the signal transceiver converter is used to be installed on the anti-UAV equipment to be detected, the signal generating device sends a test signal to the signal transceiver converter, and the controller is used to test the UAV detection function of the anti-UAV equipment according to the alarm condition of the anti-UAV equipment and the signal strength of the test signal, so as to determine whether the UAV detection function of the anti-UAV equipment is normal. In the present application, the anti-UAV equipment can be detected without relying on a darkroom, and according to the alarm condition of the anti-UAV equipment and the signal strength of the test signal, it can be quickly and effectively determined whether the UAV detection function of the anti-UAV equipment is normal.

[0037] Figure 1 FIG. 1 is a schematic diagram of an anti-UAV equipment testing system provided by an embodiment of the present application. Figure 1 As shown, the anti-UAV equipment test system 1 includes a signal transceiver converter 10, a signal generator 20 and a controller 30. The anti-UAV equipment test system 1 is used to test the anti-UAV equipment, the signal transceiver converter 10 is used to be installed on the anti-UAV equipment, the signal generator 20 is electrically connected to the signal transceiver converter 10, and the controller 30 is respectively connected to the signal generator 20 and the anti-UAV equipment for communication.

[0038] Among them, the signal transceiver converter 10 refers to a device for transmitting and receiving signals and converting signals. In some embodiments, the signal transceiver converter 10 is a near-field probe, wherein the near-field probe can be an electric field probe or a magnetic field probe. In the embodiment of the present application, preferably, the signal transceiver converter 10 is a magnetic field probe of a metal ring. According to the working principle of the magnetic field probe, in theory, the magnetic field radiated by the antenna of the anti-UAV device needs to pass through the inside of the metal ring of the magnetic field probe, and the energy induced by the near-field probe is the strongest at this time. However, in the embodiment of the present application, considering the installation position of the near-field probe and the power of the counter of the anti-UAV device to be detected, the magnetic field probe of the metal ring in the embodiment of the present application is used to flatly attach to the front of the radiating antenna of the counter. For example, if the diameter of the magnetic field probe is 17mm, determine that the fixed position of the magnetic field probe is 30cm in front of the radiating antenna of the counter. At the same time, determine that the RF routing of the magnetic field probe is 13cm away from the bottom of the anti-UAV device. It should be noted that, due to the different shapes of the countermeasures and the positions of the radiating antennas, the positions of the probes and the positions of the RF traces corresponding to different countermeasures are different. Therefore, the setting position of the signal transceiver converter 10 can be determined as needed and is not limited here.

[0039] The signal generating device 20 refers to a device for generating a test signal so as to detect the anti-UAV equipment using the test signal. The controller 30 may be a single chip microcomputer, a microcontroller unit (MCU), a programmable logic controller (PLC), a digital signal processor (DSP), a field programmable gate array (FPGA), a system on chip (SoC), etc.

[0040] The controller 30 sends a first control signal to the signal generating device 20 , and the signal generating device 20 sends a test signal to the signal transceiver converter 10 in response to the received first control signal, so that the detection antenna of the anti-UAV device receives the test signal radiated by the signal transceiver converter 10 .

[0041] The first control signal sent by the controller 30 to the signal generating device 20 is used to control the signal generating device 20 to send a test signal to the signal transceiver converter 10. After receiving the test signal, the signal transceiver converter 10 radiates the test signal so that the detection antenna in the anti-UAV device receives the test signal.

[0042] Among them, the drone will transmit signals when flying, so the anti-drone device receives the signals transmitted by the drone through the detection antenna, and thus detects the drone based on the signals transmitted by the drone. In the embodiment of the present application, the test signal is a signal that simulates the signal transmitted by the drone. It can be understood that, when the strength of the signal transmitted by the drone is consistent, the farther the drone is from the anti-drone device, the weaker the signal strength transmitted by the drone received by the anti-drone device, that is, the signal strength of the signal transmitted by the drone received by the anti-drone device is related to the distance between the drone and the anti-drone device. Therefore, if the drone is far away from the anti-drone device, the anti-drone device cannot receive the signal transmitted by the drone, or the received signal strength transmitted by the drone is weak, and the drone cannot be detected. In general, the anti-drone device can only detect drones within a certain range from it, and this range is the detectable range of the anti-drone device. Therefore, in order to detect whether the anti-drone device can normally detect drones at a certain target distance from it, a test signal of corresponding strength can be sent to the signal transceiver converter 10. Among them, the strength P of the test signal ′ According to the formula P ′=P+S21, where P is the power of the signal transmitted by the drone at the target distance that the anti-UAV device should receive, and S21 is the isolation of the signal receiving antenna of the anti-UAV device.

[0043] After the controller 30 sends a first control signal to the signal generating device 20 to control the signal generating device 20 to send a test signal to the signal transceiver converter 10, the drone detection function of the anti-drone device is tested according to the alarm status of the anti-drone device and the signal strength of the test signal.

[0044] Among them, the alarm situation includes generating an alarm message when the test signal received by the anti-UAV device is within the signal strength corresponding to the detectable range. After detecting a drone, the anti-UAV device usually generates an alarm message to prompt the user that the drone has been detected. After the anti-UAV device receives the test signal, if no alarm message is generated, it may be that the signal strength of the test signal is weak, that is, the signal strength of the test signal is lower than the signal with the weakest signal strength corresponding to the detectable range of the anti-UAV device, or the drone detection function of the anti-UAV device is abnormal and cannot detect the drone normally. If the anti-UAV device does not generate an alarm signal, and the signal strength of the test signal belongs to the signal strength corresponding to the detectable range of the anti-UAV device, it can be determined that the drone detection function of the anti-UAV device is abnormal. If the anti-UAV device does not generate an alarm signal, and the signal strength of the test signal does not belong to the signal strength corresponding to the detectable range of the anti-UAV device, that is, the signal strength of the test signal is lower than the signal with the weakest signal strength corresponding to the detectable range of the anti-UAV device, it can be determined that the drone detection function of the anti-UAV device is normal.

[0045] Therefore, if the anti-drone device does not generate an alarm message, the controller 30 determines whether the signal strength of the test signal belongs to the signal strength corresponding to the detectable range of the anti-drone device. If the signal strength of the test signal belongs to the signal strength corresponding to the detectable range, the controller 30 determines that the drone detection function of the anti-drone device is abnormal.

[0046] In the embodiment of the present application, a test signal is sent to the signal transceiver converter 10 by the signal generating device 20 in the anti-drone equipment test system 1, so that the detection antenna in the anti-drone equipment receives the test signal radiated by the signal transceiver converter 10, and then the controller 30 tests the drone detection function of the anti-drone equipment according to the alarm status of the anti-drone equipment and the signal strength of the test signal, so as to directly and quickly determine whether the drone detection function of the anti-drone equipment is normal. If the anti-drone equipment does not generate an alarm message, and the signal strength of the test signal belongs to the signal strength corresponding to the detectable range, the controller 30 can directly determine that the drone detection function of the anti-drone equipment is abnormal. The anti-drone equipment test system 1 can be used to realize the system-level function detection of the anti-drone equipment, so that the function of the anti-drone equipment before the field demonstration can be more conveniently detected, thereby improving the test efficiency.

[0047] Furthermore, in order to determine whether the anti-UAV equipment test system 1 can detect a UAV at a certain distance, by determining the strength of the test signal corresponding to the distance and sending the test signal of the strength to the signal transceiver converter 10, it is possible to determine whether the anti-UAV equipment can detect the UAV at the distance according to whether the anti-UAV equipment generates an alarm message, thereby realizing quantitative detection of the anti-UAV equipment. Furthermore, in the embodiment of the present application, the anti-UAV equipment test system 1 can be used in any scenario to detect the anti-UAV equipment, without relying on a darkroom, and is not limited by the detection environment, thereby improving the practicality of the anti-UAV equipment test system 1. Furthermore, by setting the signal transceiver converter 10, the signal generating device 20 and the controller 30 in the anti-UAV equipment test system 1, the anti-UAV equipment can be detected, thereby improving the integration of the anti-UAV equipment test system 1 and also improving the portability of the anti-UAV equipment test system 1.

[0048] In some embodiments, the controller 30 is further configured to send a second control signal to the signal generating device 20 when the anti-UAV device generates an alarm message, so as to attenuate the signal strength of the test signal output by the signal generating device 20. By reducing the signal strength of the test signal output by the signal generating device 20, it is possible to test whether the anti-UAV device can detect a UAV at a farther distance according to the alarm status of the anti-UAV device and the signal strength of the test signal.

[0049] Figure 2 FIG. 2 is a schematic diagram of an anti-UAV equipment testing system provided by another embodiment of the present application. Figure 2 As shown, in Figure 1On the basis of the provided anti-UAV equipment test system 1, in the embodiment of the present application, the signal generating device 20 includes a signal generator 21 and a first attenuator 22, wherein the output end of the signal generator 21 is electrically connected to the input end of the first attenuator 22 through a first radio frequency line 40, the output end of the first attenuator 22 is electrically connected to the signal transceiver converter 10 through a second radio frequency line 50, and the controller 30 is respectively connected to the signal generator 21 and the first attenuator 22 in communication. The controller 30 sends a first control signal to the signal generator 21, and the signal generator 21 responds to the received first control signal and sends an initial test signal to the first attenuator 22 through the first radio frequency line 40. The first attenuator 22 responds to the received initial test signal and attenuates the initial test signal to obtain a test signal, and transmits the test signal to the signal transceiver converter 10 through the second radio frequency line 50.

[0050] In the embodiment of the present application, the first attenuator 22 refers to a device for attenuating the strength of the signal received by it. The signal form of the initial test signal and the test signal is the same, but there is a difference in the signal strength of the two. As described above, there is a corresponding relationship between the strength of the signal transmitted by the drone received by the anti-drone device and the distance between the drone and the anti-drone device. The farther the drone is, the weaker the strength of the signal transmitted by the drone received by the anti-drone device. In order to test whether the anti-drone device can detect a drone at a long distance through the anti-drone device test system 1, if the signal generator 21 cannot output a test signal with a weak signal strength, in the embodiment of the present application, by setting the first attenuator 22 in the anti-drone device test system 1, the initial test signal output by the signal generator 21 is attenuated by the first attenuator 22 to obtain a test signal with a weak signal strength, so that the test signal with a weak signal strength can be used to detect whether the anti-drone device can detect a drone at a long distance.

[0051] exist Figure 2 On the basis of the provided anti-UAV equipment testing system, in an embodiment of the present application, the first attenuator 22 is a first adjustable attenuator, and the controller 30 is communicatively connected to the first adjustable attenuator. Figure 3 The following is a schematic diagram showing the steps performed by the controller according to the embodiment of the present application. Figure 3As shown, the controller 30 sends a first control signal to the signal generator 21 (1001), and determines whether the anti-UAV device generates an alarm message (1002). If the alarm message is generated, the controller 30 sends a second control signal to the first adjustable attenuator to increase the attenuation value of the first adjustable attenuator (1003), and determines whether the anti-UAV device generates an alarm message after the attenuation value of the first adjustable attenuator is increased (1004). If the anti-UAV device does not generate an alarm message after the attenuation value of the first adjustable attenuator is increased, the controller 30 determines whether the current attenuation value of the first adjustable attenuator is less than or equal to the first threshold value (1005). If the current attenuation value is less than or equal to the first threshold value, it is determined that the UAV detection function of the anti-UAV device is abnormal (1006). If the current attenuation value is greater than the first threshold value, it is determined that the UAV detection function of the anti-UAV device is normal (1007). If the anti-UAV device generates an alarm message after the attenuation value of the first adjustable attenuator is increased, the controller sends a second control signal to the first adjustable attenuator to increase the attenuation value of the first adjustable attenuator (1003). If the anti-UAV device does not generate an alarm message after sending the first control signal (1001) to the signal generator 21, the controller 30 determines whether the current attenuation value of the first adjustable attenuator is less than or equal to the first threshold value (1005), and determines that the UAV detection function of the anti-UAV device is abnormal (1006) or determines that the UAV detection function of the anti-UAV device is normal (1007) based on the judgment result.

[0052] The first adjustable attenuator refers to an attenuator whose attenuation value is a non-fixed value and whose attenuation value can be adjusted. After the signal generator 21 generates an initial test signal of a certain signal strength, the strength of the test signal output by the first adjustable attenuator can be reduced by increasing the attenuation value of the first adjustable attenuator. The amplitude of the attenuation value increased by the first adjustable attenuator each time can be pre-set, so that the first adjustable attenuator increases the attenuation value according to the pre-set amplitude each time it receives the second control signal sent by the controller 30. For example, the amplitude of the attenuation value increased by the first adjustable attenuator each time can be set to 10% or 20%.

[0053] In the embodiment of the present application, after the controller 30 sends the first control signal to the signal generator 21, the signal generator 21 responds to the received first control signal and sends an initial test signal to the first adjustable attenuator, so that the first adjustable attenuator sends the test signal to the signal transceiver converter 10. If the anti-UAV device generates an alarm message after receiving a test signal of a certain strength, the controller 30 controls the first adjustable attenuator to increase the attenuation value to reduce the strength of the test signal output by the first adjustable attenuator, thereby simulating the signal transmitted by the UAV farther from the anti-UAV device, so as to perform a comprehensive test on the UAV detection function of the anti-UAV device, thereby avoiding the situation that the anti-UAV device can detect a UAV at a closer distance, but cannot detect a UAV at a farther distance but still within the detection range of the anti-UAV device, thereby improving the detection accuracy of the anti-UAV device. In addition, in the embodiment of the present application, by adjusting the attenuation value of the first adjustable attenuator, the signal strength of the test signal output by the first adjustable attenuator can be adjusted, so that the signal transmitted by the UAV at different distances can be simulated, thereby improving the detection efficiency of the UAV detection function of the anti-UAV device.

[0054] Figure 4 A schematic diagram of an anti-UAV equipment testing system provided by another embodiment of the present application is shown. Figure 4 As shown, in Figure 1 On the basis of the anti-UAV equipment test system provided, in the embodiment of the present application, the anti-UAV equipment test system 1 further includes a spectrum analyzer 60, the signal transceiver converter 10 is electrically connected to the spectrum analyzer 60 via a third radio frequency line 70, and the controller 30 is communicatively connected to the spectrum analyzer 60. The signal transceiver converter 10 receives the counter signal sent by the anti-UAV equipment when it is in the counter mode, and transmits it to the spectrum analyzer 60 via the third radio frequency line 70. The spectrum analyzer 60 receives the counter signal, determines the frequency band and power of the counter signal, and transmits the frequency band and power of the counter signal to the controller 30.

[0055] Among them, the anti-UAV device usually counters the UAV by transmitting a high-power counter signal with the same communication frequency as the UAV to the UAV. Therefore, the coverage of the frequency bandwidth of the counter signal output by the anti-UAV device and the power of the counter signal are the key factors for whether the anti-UAV device can successfully counter the UAV. It can be understood that an anti-UAV device can have multiple different counter modes, and each counter mode corresponds to a different counter frequency band. For example, the anti-UAV device includes 2 counter modes, the first counter mode corresponds to the first counter frequency band and the second counter frequency band, and the second counter mode corresponds to the third counter frequency band and the fourth counter frequency band. When the anti-UAV device is in the first counter mode, it outputs the counter signal of the first counter frequency band and the second counter frequency band to counter the UAV whose communication frequency belongs to the first counter frequency band and the second counter frequency band. When the anti-UAV device is in the second counter mode, it outputs the counter signal of the third counter frequency band and the fourth counter frequency band to counter the UAV whose communication frequency belongs to the third counter frequency band and the fourth counter frequency band.

[0056] The spectrum analyzer 60 is used to analyze the frequency and power of the received counter-signal, and can display a distribution diagram of the power of the counter-signal relative to the frequency.

[0057] Figure 5 FIG. 2 is a schematic diagram showing a flow chart of steps performed by a controller according to another embodiment of the present application. Figure 5 As shown, in an embodiment of the present application, the controller 30 is used to determine whether the frequency band of the counter-attack signal includes at least one frequency in each counter-attack frequency band corresponding to the counter-attack mode (2001). If the frequency band of the counter-attack signal does not include at least one frequency in each counter-attack frequency band corresponding to the counter-attack mode, it is determined that the drone counter-attack function of the anti-drone device is abnormal (2002).

[0058] As described above, when the anti-UAV device is in a certain countermeasure mode, the anti-UAV device should output the signal of each countermeasure frequency band corresponding to the countermeasure mode. Therefore, in the embodiment of the present application, the controller 30 can quickly determine whether the UAV countermeasure function of the anti-UAV device is normal by judging whether the frequency band of the countermeasure signal output by the anti-UAV device includes at least one frequency in each countermeasure frequency band corresponding to the countermeasure mode. For example, if the countermeasure frequency band corresponding to the countermeasure mode is 2.4-2.5GHz and 5-5.8GHz, as long as the frequency of the countermeasure signal output by the anti-UAV device does not include one of the frequencies within 2.4-2.5GHz or does not include one of the frequencies within 5-5.8GHz, the controller 30 determines that the UAV countermeasure function of the anti-UAV device is abnormal.

[0059] In some embodiments, if the frequency band of the countermeasure signal includes at least one frequency in each countermeasure frequency band corresponding to the countermeasure mode, the controller 30 determines whether the frequency band of the countermeasure signal includes all frequencies in the countermeasure frequency band corresponding to the countermeasure mode (2003). If the frequency band of the countermeasure signal does not include all frequencies in the countermeasure frequency band corresponding to the countermeasure mode, the controller 30 determines that the drone countermeasure function of the anti-drone device is abnormal (2002).

[0060] Among them, when the anti-UAV device is in a certain counter-attack mode, the frequency band of the counter-attack signal output by the anti-UAV device only includes all frequencies in the counter-attack frequency band corresponding to the counter-attack mode, so as to effectively counter the UAV whose communication frequency belongs to the counter-attack frequency band. For example, if the counter-attack frequency band corresponding to the counter-attack mode is 2.4-2.5GHz and 5-5.8GHz, the frequency band of the counter-attack signal output by the anti-UAV device only includes all frequencies in 2.4-2.5GHz and 5-5.8GHz, so as to effectively counter the UAV whose communication frequency belongs to the frequency within 2.4-2.5GHz and 5-5.8GHz. If the frequency band of the counter-attack signal output by the anti-UAV device is 2.45-2.5GHz and 5.5-5.8GHz, then it is impossible to effectively counter the UAV whose communication frequency belongs to the frequency within 2.4-2.45GHz and 5-5.5GHz.

[0061] Therefore, in the embodiment of the present application, the controller 30 can quickly and accurately determine whether the drone counter-function of the anti-drone device is normal by judging whether the frequency band of the counter-signal includes all frequencies in the counter-signal frequency band corresponding to the counter-signal mode. If the frequency band of the counter-signal does not include all frequencies in the counter-signal frequency band corresponding to the counter-signal mode, it can be accurately determined that the drone counter-function of the anti-drone device is abnormal.

[0062] In some embodiments, if the frequency band of the countermeasure signal includes all frequencies in the countermeasure frequency band corresponding to the countermeasure mode, the controller 30 determines whether the power of the countermeasure signal of each countermeasure frequency band in the countermeasure signal is less than or equal to the second threshold value corresponding to the countermeasure frequency band (2004). If there is a countermeasure signal of a countermeasure frequency band whose power is less than or equal to the second threshold value corresponding to the countermeasure frequency band, the controller 30 determines that the drone countermeasure function of the anti-drone device is abnormal (2002). If the power of the countermeasure signal of each countermeasure frequency band is greater than the second threshold value corresponding to the countermeasure frequency band, the controller 30 determines that the drone countermeasure function of the anti-drone device is normal (2005).

[0063] As introduced above, the power of the counter signal output by the anti-UAV device is a key factor affecting whether it can successfully counter the UAV. Only when the power of the counter signal output by it reaches a certain level can it effectively counter the UAV. In the embodiment of the present application, if the anti-UAV device has multiple different counter modes, each counter mode corresponds to a different counter frequency band, and each counter frequency band corresponds to a different second threshold value, the controller 30 can accurately and quickly determine whether the UAV counter function of the anti-UAV device is normal by judging the power of the counter signal of each counter frequency band and the second threshold value corresponding to the counter frequency band, wherein the second threshold value can be determined as needed and is not limited here. If the power of the counter signal of a certain counter frequency band is less than or equal to the second threshold value corresponding to the counter frequency band, the controller 30 can accurately determine that the UAV counter function of the anti-UAV device is abnormal. For example, the countermeasure mode in the embodiment of the present application corresponds to a first countermeasure frequency band and a second countermeasure frequency band, the first countermeasure frequency band corresponds to a first second threshold, and the second countermeasure frequency band corresponds to a second second threshold. If the power of the countermeasure signal of the first countermeasure frequency band output by the anti-UAV device is less than or equal to the first second threshold, and / or the power of the countermeasure signal of the second countermeasure frequency band output by the anti-UAV device is less than or equal to the second second threshold, it is determined that the UAV countermeasure function of the anti-UAV device is abnormal.

[0064] Figure 6 FIG. 2 is a schematic diagram of an anti-UAV equipment testing system provided by another embodiment of the present application. Figure 6 As shown, the third RF line 70 includes a fourth RF line 71 and a fifth RF line 72, the anti-UAV equipment test system 1 includes a second attenuator 80, the output end of the signal transceiver converter 10 is electrically connected to the input end of the second attenuator 80 through the fourth RF line 71, and the output end of the second attenuator 80 is electrically connected to the spectrum analyzer 60 through the fifth RF line 72.

[0065] Since the power of the counter signal output by the anti-UAV equipment test system is relatively large, in the embodiment of the present application, a second attenuator 80 is added between the signal transceiver converter 10 and the spectrum analyzer 60 to attenuate the power of the counter signal sent by the signal transceiver converter 10, thereby preventing the spectrum analyzer 60 from being damaged by the counter signal with excessive power. It should be noted that the attenuation value of the second attenuator 80 can be set as needed, for example, to 20dB or 30dB. In the embodiment of the present application, preferably, the attenuation value of the second attenuator 80 is 30dB.

[0066] Figure 7 FIG. 2 is a schematic diagram of an anti-UAV equipment testing system provided by another embodiment of the present application. Figure 7As shown, the signal generating device 20 includes a dark box 23, a drone 24, a signal receiving antenna 25 and a second adjustable attenuator 26. The drone 24 and the signal receiving antenna 25 are arranged in the dark box 23, the signal receiving antenna 25 is electrically connected to the input end of the second adjustable attenuator 26 through the sixth radio frequency line 90, the output end of the second adjustable attenuator 26 is electrically connected to the signal transceiver converter 10 through the seventh radio frequency line 100, and the drone 24 is communicatively connected to the controller 30. The controller 30 sends a first control signal to the drone 24. In response to receiving the first control signal, the drone 24 transmits an initial test signal. The signal receiving antenna 25 receives the initial test signal and transmits the initial test signal to the second adjustable attenuator 26 through the sixth radio frequency line 90. In response to receiving the initial test signal, the second adjustable attenuator 26 attenuates the initial test signal to obtain a test signal, and transmits the test signal to the signal transceiver converter 10 through the seventh radio frequency line 100.

[0067] In the embodiment of the present application, the dark box 23 is used to shield the drone signal. By placing the drone 24 and the signal receiving antenna 25 in the dark box 23, after the drone 24 transmits the initial test signal, the signal receiving antenna 25 can receive the initial test signal. The signal receiving antenna 25 transmits the initial test signal to the second adjustable attenuator 26 through the sixth radio frequency line 90. By adjusting the attenuation value of the second adjustable attenuator 26, the signal strength of the test signal output by the second adjustable attenuator 26 can be adjusted, so that signals of different signal strengths emitted by drones at different distances can be simulated, so as to realize the detection of the drone detection function of the anti-drone device through the anti-drone device test system 1. Among them, the working principle and function of the second adjustable attenuator 26 are similar to those of the first adjustable attenuator, which will not be repeated here.
