Description

Technical Field

Background Art

[0002] The working principle of radar is to transmit electromagnetic waves. When the electromagnetic waves encounter a target during the propagation path, they cannot completely penetrate, so part of the electromagnetic waves will be reflected from the target surface. The radar then uses the design of the internal hardware circuit to receive the reflected signal and compare the characteristics with the transmitted signal to extract various parameters of the target. The target parameters that generally need to be known are mainly the distance to the target, the azimuth of the target, and the movement speed of the target.

[0003] In actual radar products, to verify the actual performance of the radar, an ideal flat and wide outdoor test site is usually found. During the test, parameters such as target distance, target angle, and target speed are calibrated. After the radar detects the target, manual measurement is performed to determine whether the actual value is consistent with the radar measurement value.

[0004] However, the above test method has a relatively complicated test process, high test cost, large test error and low test accuracy; at the same time, it cannot effectively implement the test of long-distance and wide-angle radar. Utility Model Content

[0039] In actual radar products, to verify the radar's true performance, an ideal, flat, and wide outdoor test site is typically found. During testing, parameters such as target distance, target angle, and target speed are calibrated. After the radar detects the target, manual measurements are performed to determine whether the actual values ​​match the radar measurements. It should be noted that the purpose of radar testing is to ensure the accuracy and reliability of the radar system and to optimize radar performance to meet the needs of specific applications.

[0040] The testing method of the related technology has a relatively complicated testing process and requires a large testing cost. It is very difficult to find a testing site that meets the requirements, and there are large testing errors in manual measurement. Outdoor testing sites will inevitably have other external interferences. Therefore, the actual testing accuracy of the above-mentioned testing method is not high. Moreover, due to cost considerations, the above-mentioned testing method is usually suitable for short-range radar testing and cannot be used to test long-range and wide-angle radars. The test is relatively limited and cannot ensure that different models of radars can be tested. The long-term reliability of the radar cannot be well guaranteed.

[0041] To address the above-mentioned technical issues, embodiments of the present application provide a radar simulation device and vehicle, wherein the radar to be tested and the radar simulator are arranged relative to each other and electrically connected. In this way, the radar simulator can perform performance testing on the radar to be tested, thereby helping to comprehensively evaluate the overall performance of the radar to be tested, and to improve and optimize it, simplifying the testing process, reducing testing costs, and maximizing test accuracy. Furthermore, the present application can be applied to testing radars at different distances, thus extending its applicability and ensuring the long-term reliability of the radar to be tested. Furthermore, arranging the radar to be tested and the radar simulator relative to each other helps improve the alignment between the radar to be tested and the radar simulator, thereby maximizing the radar simulator's testing accuracy on the radar to be tested and achieving precision in the performance testing of the radar to be tested.

[0042] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] An embodiment of the present application provides a vehicle, which includes at least a vehicle body and a radar simulation device.

[0044] For example, the vehicle may be an intelligent self-driving vehicle, or an ordinary human-driven vehicle, such as a car, a truck, a trailer, or a flatbed truck, etc. This is not limited in this embodiment.

[0045] In the embodiment of the present application, the radar simulation device can be installed on the vehicle body. There is no further limitation on the setting of the radar simulation device, and it can be set according to actual needs.

[0046] In the embodiments of this application, the connection method between the radar simulator and the vehicle body is not limited. For example, the radar simulator and the vehicle body can be connected via a connector. For example, the connector can be a bolt, stud, screw, or rivet. This embodiment does not limit this.

[0047] It should be noted that the radar simulation device in this embodiment includes but is not limited to being installed on a vehicle.

[0048] For example, a radar simulator can be installed on a ship. By simulating different environments and conditions such as ship positioning, avoidance operations, radar images, intersecting ships, wind currents, waves, rain and snow interference, etc., the radar simulator can provide a training platform close to the real operating environment, allowing operators to learn and improve their radar operating skills in a simulated environment.

[0049] For example, when a radar simulator is installed on a vehicle, it can help improve driving safety and enhance driving convenience. For example, the radar simulator can also be used for radar operation training in aircraft and other fields, thereby providing a safe and economical training method and helping to avoid the dangers and cost issues that may be encountered in actual operation. This embodiment is not limited to this.

[0050] In an embodiment of the present application, a radar simulation device is used to simulate a radar to be tested. It should be noted that the test process between the radar simulation device and the radar to be tested is as follows: the radar simulator generates an echo signal through data communication between a host computer and the radar to be tested. Specifically, the radar sensor to be tested sends a radar signal to the receiving antenna of the radar simulator, the radar signal is received in the radar simulator, the radar signal is filtered in the radar simulator with the aid of a low-pass filter, and the simulated radar echo signal is sent from the transmitting antenna of the radar simulator to the radar sensor to be tested, thereby achieving the purpose of truly reproducing the radar echo signal.

[0051] Among them, by simulating echo signals under different conditions, the performance of the radar in different environments can be tested, including the ability to detect, track, and identify targets; in addition, the radar simulator can also simulate interference signals in complex environments to test the radar's anti-interference ability, thereby comprehensively evaluating the overall performance of the radar system.

[0052] The specific structure of the radar to be tested is not limited. For example, the radar simulation device in this embodiment can be used to test the performance of a 24 GHz millimeter wave radar. This embodiment does not limit this.

[0053] The structure of the radar simulation device provided in this application is described in detail below.

[0054] Reference Figures 1 to 9 As shown, the radar simulation device includes a cabinet 110, which includes a cabinet body 111 and a mounting platform 112. A test chamber 120 is disposed in the cabinet body 111, and a radar simulator 121 is mounted in the test chamber 120. A radar to be tested 130 is disposed on the mounting platform 112, and the radar to be tested 130 is disposed opposite to and electrically connected to the radar simulator 121.

[0055] In this embodiment, test chamber 120, constructed with designed absorbing materials, eliminates false targets that appear during target simulation, ensuring test accuracy and reliability. This type of test chamber 120 is commonly used for radar and antenna testing, providing a controlled environment and reducing external interference, thereby accurately measuring radar characteristics and helping to minimize interference from external electromagnetic signals on test results.

[0056] In the embodiment of the present application, the radar under test 130 and the radar simulator 121 are positioned relative to each other. For example, they can be positioned face-to-face, so that there is no obstruction between the radar under test 130 and the radar simulator 121. This allows the radar under test 130 to immediately receive signals from the radar simulator 121 during testing, facilitating rapid response and detection, reducing test preparation time and operational complexity. Furthermore, this arrangement allows testers to observe and record the responses of the radar under test 130 in real time, allowing for rapid performance evaluation and further accelerating the testing process.

[0057] In the embodiment of the present application, the electrical connection method between the radar under test 130 and the radar simulator 121 is not limited. For example, the radar under test 130 and the radar simulator 121 may be electrically connected via a wired connection; alternatively, the radar under test 130 and the radar simulator 121 may be electrically connected via a wireless connection. This embodiment does not impose any limitations on this.

[0058] In the embodiment of the present application, the radar under test 130 has a signal transmitting end, which is located on the side of the radar under test 130 facing the test darkroom 120 , and the radar simulator 121 has a signal receiving end, which is located on the side of the radar simulator 121 facing the mounting platform 112 .

[0059] The radar to be tested 130 is configured to transmit a radar signal to the radar simulator 121 through a signal transmitting end. The radar simulator 121 is configured to receive the radar signal through a signal receiving end and generate an echo signal.

[0060] Radar simulator 121 is also configured to test radar 130 by simulating echo signals. For example, this can test the adaptability of radar 130 in complex electromagnetic environments, ensuring its reliability and effectiveness in practical applications. Furthermore, it can simulate targets, environments, and interference signals for radar 130, thereby meeting the testing requirements of different radar types.

[0061] Therefore, the radar simulation device provided in this embodiment helps to comprehensively evaluate the overall performance of the radar to be tested, and to improve and optimize it, simplify the testing process, reduce testing costs, and maximize test accuracy; at the same time, the present application can be applied to the testing of radars of different distances, with a wider scope of application, ensuring the long-term reliability of the radar to be tested.

[0062] In one possible implementation, referring to Figure 1 and Figure 2 As shown, a radar fixing part 140 may also be included. The radar fixing part 140 is disposed on the mounting platform 112 . The radar fixing part 140 is used to fix the radar 130 to be tested and adjust the position of the radar 130 to be tested.

[0063] In the embodiment of the present application, there is no limitation on the connection method between the radar fixture 140 and the mounting platform 112. For example, the radar fixture 140 and the mounting platform 112 may be detachably connected by screws or the like. This facilitates installation and removal of the radar fixture 140 and facilitates installation and adjustment of the radar under test 130.

[0064] In the embodiment of the present application, the method for adjusting the position of the radar under test 130 is not limited. For example, the radar fixing member 140 may be a radar fixing bracket, which may be equipped with an adjustable height setting. By rotating or sliding an adjustment button on the radar fixing bracket, the height of the radar fixing bracket can be easily changed, thereby facilitating adjustment of the position of the radar under test 130. This embodiment is not limited to this.

[0065] In the embodiment of the present application, the orthographic projection of the radar fixture 140 on the plane where the test darkroom 120 is located is misaligned with the orthographic projection of the radar 130 to be tested on the plane where the test darkroom 120 is located and with the radar simulator 121 .

[0066] It can be understood that orthographic projection misalignment means that when two objects or structures are projected onto the same plane, their projection positions or shapes do not completely overlap, and there is a position deviation or shape mismatch.

[0067] In this way, on the one hand, by arranging the projections of the two structures in a staggered manner, every available position can be maximized within a limited space, and overlap between structures can be avoided, thereby making the entire spatial layout more compact and efficient, and improving space utilization; on the other hand, when the orthographic projections of two structures on the same plane are staggered, their actual positions in the physical space will also be staggered accordingly, which can effectively avoid direct contact or interference between the structures, and can reduce the impact of adverse factors such as vibration and heat transfer on structural performance, thereby improving the overall stability and reliability of the system.

[0068] In one possible implementation, referring to Figure 1 、 Figure 2 as well as Figure 7 As shown, the radar fixing member 140 can be an annular structure, surrounding the outer circumference of the radar under test 130. The shape of the radar fixing member 140 is not limited. For example, the radar fixing member 140 can be a square ring structure or a circular ring structure. Any shape matching the radar fixing member 140 to the radar under test 130 falls within the scope of protection of this application. This helps improve the fixing effect of the radar fixing member 140 on the radar under test 130, thereby ensuring detection accuracy.

[0069] In the embodiment of the present application, there is no limitation on the mounting method of the radar fixture 140 and the radar under test 130. For example, the radar under test 130 may be provided with a buckle, and the radar fixture 140 may be provided with a slot; or, the radar under test 130 may be provided with a slot, and the radar fixture 140 may be provided with a buckle.

[0070] In this embodiment, refer to Figure 1 and Figure 2 As shown, the following mainly uses the example of a buckle 131 provided on the radar under test 130 and a slot 141 provided on the radar fixture 140. Thus, the corresponding engagement of the slot 141 and the buckle 131 helps to improve the installation stability of the radar fixture 140 and the radar under test 130, and also facilitates the assembly and disassembly of the radar under test 130.

[0071] For example, the radar fixing member 140 and the radar under test 130 may be connected by bonding, or the radar fixing member 140 and the radar under test 130 may be connected by screws, etc. This embodiment does not limit this.

[0072] In one possible implementation, referring to Figure 3 As shown, a simulator fixing part 150 may also be included. The simulator fixing part 150 is installed in the test dark box 120 . The simulator fixing part 150 is used to fix the radar simulator 121 and adjust the position of the radar simulator 121 .

[0073] The orthographic projection of the simulator fixture 150 on the plane where the mounting platform 112 is located is misaligned with the orthographic projection of the radar simulator 121 on the plane where the mounting platform 112 is located and with the radar to be tested 130 .

[0074] In this way, every available position can be maximized within a limited space, and overlap between structures can be avoided, making the entire space layout more compact and efficient, thereby improving space utilization. In addition, this can effectively avoid direct contact or interference between structures, and can reduce the impact of adverse factors such as vibration and heat transfer on structural performance, thereby improving the overall stability and reliability of the system.

[0075] In one possible implementation, referring to Figure 3 As shown, the simulator fixing part 150 may include a supporting part 151 and at least two limiting parts 152 , the radar simulator 121 is mounted on the supporting part 151 , and at least two limiting parts 152 surround the outer periphery of the supporting part 151 , and the limiting parts 152 are used to limit the supporting part 151 .

[0076] In this embodiment of the present application, the assembly method of the support portion 151 and the radar simulator 121 is not limited. For example, the radar simulator 121 can be fixedly mounted on the support portion 151; alternatively, the radar simulator 121 and the support portion 151 can be connected by means of a snap-fit, screw connection, or other similar method. This embodiment does not impose any restrictions on this. In this way, the support portion 151 provides basic support and mounting, thereby improving stability during the detection process.

[0077] In the embodiment of the present application, there is no limitation on the number of the limiting parts 152. For example, the limiting parts 152 may include two, and the two limiting parts 152 are respectively located on both sides of the supporting part 151, which helps to limit the supporting part 151, and further helps to further fix the radar simulator 121, preventing the radar simulator 121 from shifting during the detection process, and ensuring the accuracy of the detection to the greatest extent.

[0078] In this embodiment of the present application, the height of the stopper 152 on the side closest to the radar under test 130 can be lower than that of the support portion 151. This helps ensure that the radar simulator 121 can effectively detect the radar under test 130, taking into account the operating environment and functional requirements of the radar simulator 121. Furthermore, this design not only facilitates adjustment of the position of the radar simulator 121 to accommodate different detection requirements, but also prevents the stopper 152 from interfering with the signal of the radar simulator 121.

[0079] The structures of the limiting portion 152 and the supporting portion 151 are not further limited. For example, the limiting portion 152 may be a limiting platform, and the supporting portion 151 may be a supporting platform. In addition, the dimensions of the limiting portion 152 and the supporting portion 151 are not limited and can be set according to actual needs.

[0080] In one possible implementation, referring to Figure 3 As shown, a dark box bracket 160 may also be included. The dark box bracket 160 is installed in the cabinet 111 . The test dark box 120 is connected to the dark box bracket 160 . The dark box bracket 160 is used to support the test dark box 120 and adjust the position of the test dark box 120 .

[0081] In the embodiment of the present application, there is no limitation on the structure of the darkroom support 160. For example, the darkroom support 160 may be a frame-like structure, including a plurality of crossbeams 161 and vertical beams 162. The vertical beams 162 support and connect the plurality of crossbeams 161, thereby helping to improve the structural strength of the darkroom support 160 and thereby ensure the installation stability of the test darkroom 120.

[0082] In a feasible implementation, a one-way hole may be provided on a wall of the test dark box 120 , and the one-way hole is configured to provide a non-reflective test environment for the test dark box 120 .

[0083] It should be noted that the one-way hole in this embodiment functions like a one-way valve, which can maintain the balance of internal and external air pressure during the test. Through this design, it is possible to maintain the stability of the internal test environment while avoiding interference from the external environment, thereby ensuring the accuracy of the test results.

[0084] In the embodiment of the present application, there is no limitation on the number and location of the one-way holes, and they can be set according to actual needs.

[0085] In one possible implementation, referring to Figures 1 to 6 As shown, a display cabinet 170 may also be included. The display cabinet 170 is disposed on the cabinet 110 . The display cabinet 170 is used to place a display 172 . The display 172 is configured to display parameters of the radar simulator 121 .

[0086] Reference Figure 1 and Figure 2 As shown, the display cabinet 170 may be provided with a heat dissipation structure 171, which is used to dissipate the heat released by the display 172. In this way, the display 172 can be effectively cooled, ensuring the normal operation of the display 172 and extending its service life.

[0087] In addition, the test dark box 120 and the cabinet 110 may be provided with a heat dissipation structure for dissipating the heat of the radar simulator 121. In this way, the radar simulator 121 can be effectively cooled, ensuring the normal operation of the radar simulator 121 and extending its service life.

[0088] For example, the heat dissipation structure 171 may be a heat sink, or a heat dissipation louver, or other structures having a heat dissipation function, which are not limited in this embodiment.

[0089] In one possible implementation, referring to Figure 2 As shown, a controller and a host 180 may also be included. The controller is configured to control the working state of the radar simulator 121, and the host 180 is configured to perform parameter processing.

[0090] The controller controlling the working state of the radar simulator 121 may include: controlling the start or stop of the radar simulator 121, which is not limited in this embodiment; or, the controller may also control the working state of other electrical components.

[0091] The host 180 performs parameter processing. For example, the host 180 is connected to the radar under test 130. For example, the host 180 can be used for data input, collection, processing, feedback, and output, etc., which is not limited in this embodiment. For example, the host 180 and the radar under test 130 can be connected via an aviation connector 174.

[0092] In the present application, refer to Figures 1 to 6 ,as well as Figure 9 As shown, the radar simulation device may further include an alarm 173 , which is electrically connected to the controller. The alarm 173 is configured to send an alarm signal when the parameters of the radar simulator 121 are unqualified.

[0093] For example, the alarm 173 may be a warning light; or, the alarm 173 may be a visual alarm, an audible alarm, a tactile alarm, or an olfactory alarm. The configuration of the alarm 173 may ensure that the alarm signal has sufficient intensity to attract the operator's attention, or has a distinct and specific shape.

[0094] In one possible implementation, referring to Figures 1 to 4 As shown, the bottom of the cabinet 110 may be provided with travel wheels 116, and a locking mechanism may be provided on the travel wheels 116. For example, the travel wheels 116 may be rollers, steering wheels, drive wheels, driven wheels, etc.; the locking mechanism may be a mechanical lock or an electronic lock, which is not limited in this embodiment and may be configured according to actual circumstances.

[0095] In this way, by setting the traveling wheels 116, it is convenient to push the movement of the cabinet 110. In addition, by setting the locking mechanism, the stability and stability of the cabinet 110 in complex environments can be improved, and the risk of slipping can be avoided, thereby ensuring the working stability of the radar simulator 121 and the radar to be tested 130 to the greatest extent, and ensuring the detection accuracy of the radar simulator 121.

[0096] In one possible embodiment, the cabinet 110 has a cabinet door 115. Opening the cabinet door 115 facilitates assembly and commissioning of the internal structure of the cabinet 110.
