Description

Technical Field

[0001] This invention relates primarily to the field of radar countermeasures technology, specifically to an airborne radar jamming method, device, and storage medium. Background Technology

[0002] Currently, many military aircraft are equipped with airborne AESA (Active AESA) radar. Compared with conventional airborne radar, AESA radar uses solid-state active adaptive phased array antennas and adopts advanced space-time adaptive signal processing technology (STAP). It has strong adaptive capabilities, beam scanning without inertia, multiple beams, high power, and fast and flexible control of beam direction and shape. It can adaptively manage space, time, and energy optimally. It has a large field of view and good concealment. It can use both omnidirectional tracking and scan-while-tracking modes. Under active jamming conditions, the sidelobe nulls of the phased array antenna can quickly point towards the enemy's jamming source, making it difficult for the enemy to receive the radar signal and thus unable to carry out effective jamming. Phased array radar has high reliability. Its solid-state active phased array antenna is equipped with a large number of independent receive / transmit (T / R) components. The failure of a few components has little impact on the overall system performance, and it has fault softening capabilities, which improves the reliability of airborne radar (compared to conventional radar) by several orders of magnitude. In particular, anti-interference technologies such as sidelobe cancellation, ultra-low sidelobe antennas, and beam lobe adaptive null control greatly limit the long-range support interference that traditionally relies on high-power sidelobe interference technology.

[0003] Electronic countermeasures involve launching corresponding electronic jamming or attacks against one or more specific target radiation sources, thereby preventing them from receiving or correctly receiving useful signals or information. However, most current electronic countermeasures methods, in order to ensure effective interference with the target, employ large-scale coverage jamming in the space-time-frequency domain. This often severely impacts other electronic systems in or around the target radiation source, and may even cause electromagnetic collateral damage to friendly electronic systems, while also reducing jamming efficiency. Therefore, current jamming methods cannot guarantee effectiveness against anti-jamming technologies such as AESA radar sidelobe cancellation, ultra-low sidelobe antennas, and lobe adaptive null control. A common countermeasure is to increase the equivalent radiated power, but increasing power introduces new problems to the overall equipment development cost and battlefield survivability.

Detailed Implementation

[0013] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0014] Figure 1 This is a flowchart illustrating an airborne radar jamming method provided in an embodiment of the present invention.

[0015] like Figure 1As shown, an airborne radar jamming method includes the following steps: S1: Detect the signals emitted by the airborne radar and obtain radar signal data; S2: Perform interference range sequence analysis on the radar signal data to obtain the interference range sequence; S3: Perform Doppler sequence analysis on the radar signal data to obtain the Doppler sequence; S4: Perform range power sequence analysis on the radar signal data to obtain multiple range power sequences; S5: Calculate the interference signal from the radar signal data, the interference range sequence, the Doppler sequence, and all the range power sequences to obtain the initial airborne radar interference signal; S6: Upconvert the initial airborne radar jamming signal to obtain the target airborne radar jamming signal.

[0016] It should be understood that the target radar signal is detected to obtain the frequency fc, bandwidth B, signal amplitude A, and signal direction of arrival. Parameters such as radar signal data are measured.

[0017] Specifically, the jamming signal (i.e. the initial airborne radar jamming signal) is up-converted and then transmitted through an antenna.

[0018] In the above embodiments, radar signal data is obtained by detecting the signals emitted by the airborne radar. An interference range sequence is obtained by analyzing the interference range sequence of the radar signal data. A Doppler sequence is obtained by analyzing the Doppler sequence of the radar signal data. A range power sequence is obtained by analyzing the range power sequence of the radar signal data. An initial airborne radar interference signal is calculated from the interference signals of the radar signal data, interference range sequence, Doppler sequence, and range power sequence. The target airborne radar interference signal is obtained by up-conversion processing of the initial airborne radar interference signal. This achieves target protection while interfering with the radar, thereby achieving covert interference with the airborne radar. At the same time, it can prevent the interference signal from being detected by the radar, greatly improving the precision interference capability.

[0019] Optionally, as an embodiment of the present invention, the radar signal data includes radar bandwidth, and the process of performing interference range sequence analysis on the radar signal data to obtain the interference range sequence includes: The radar range resolution is obtained by calculating the radar bandwidth using the first equation, which is: , in, For radar range resolution, At the speed of light, Radar bandwidth; The interference range sequence is obtained by calculating the radar range resolution using the second equation, which is: , in, Preset number of sequences Interference distance sequence, For radar range resolution, The preset number of sequences.

[0020] It should be understood that, to estimate the radar range resolution, considering the material and angle of the protected target, an interference peak power reference is generated. Taking into account the radar sampling rate, this is typically estimated at 1.2 times the theoretical radar resolution, as shown in the following formula: .

[0021] Specifically, based on the distance, an interference distance sequence is formed. The number of sequences is N (i.e., the preset number of sequences), and N is usually an odd number between 5 and 10, as shown in the following formula: .

[0022] In the above embodiments, interference range sequence analysis is performed on radar signal data to obtain interference range sequence, which achieves both target protection and radar interference, thereby achieving covert interference with airborne radar targets.

[0023] Optionally, as an embodiment of the present invention, the radar signal data includes the radar pulse repetition frequency and the number of radar pulse coherent accumulations; The process of performing Doppler sequence analysis on the radar signal data to obtain the Doppler sequence includes: The target radar Doppler resolution is obtained by calculating the radar pulse repetition frequency and the radar pulse coherent accumulation number using the third equation, which is: , in, For target radar Doppler resolution, The radar pulse repetition frequency, The number of radar pulse coherent accumulations; The Doppler resolution of the target radar is calculated using the fourth equation to obtain the Doppler sequence. The fourth equation is as follows: , in, Preset number of sequences Doppler sequences, For target radar Doppler resolution, The preset number of sequences.

[0024] It should be understood that the Doppler resolution is estimated to form a Doppler sequence (i.e., the target radar Doppler resolution), as follows: , in, To estimate the target radar Doppler resolution, The measured radar pulse repetition frequency, The number of radar pulses coherently accumulated for measurement.

[0025] Specifically, the Doppler interference size is designed to be N times larger, forming a Doppler sequence as follows: .

[0026] In the above embodiments, Doppler sequence analysis is performed on the radar signal data to obtain the Doppler sequence, which achieves both target protection and radar interference, thereby achieving covert interference with airborne radar targets.

[0027] Optionally, as an embodiment of the present invention, the radar signal data includes the target scattering area, elevation angle of the direction of arrival, azimuth angle of the direction of arrival, receiver noise level, backscattering coefficient, and multiple sampling points; The process of performing range power sequence analysis on the radar signal data to obtain multiple range power sequences includes: The peak interference power is obtained by calculating the target scattering area, the elevation angle of the incoming wave direction, the azimuth angle of the incoming wave direction, and the backscattering coefficient using the fifth equation. The fifth equation is: , in, To interfere with peak power, For the target scattering area, The pitch angle is the direction of the incoming wave. The azimuth angle is the direction of the incoming wave. The backscattering coefficient; The sixth equation is used to calculate the peak interference power, the receiver noise level, and each sampling point, respectively, to obtain the distance power sequence corresponding to each sampling point. The sixth equation is: , in, , in, For the first The distance power sequence corresponding to each sampling point To interfere with peak power, This refers to the receiver noise level. For the target coverage size, For the preset number of sequences, These are the sampling points.

[0028] It should be understood that, for the material and angle of the protected target, an interference peak power reference is generated. (i.e., peak interference power), estimate the target's RCS value. As shown in the following formula: , where A is the target's scattering area (i.e., the target's scattering area). The pitch angle is the direction of the incoming wave (i.e., the pitch angle in the direction of the incoming wave). It is the azimuth angle of the incoming wave direction (i.e., the azimuth angle of the incoming wave direction). denoted as the backscattering coefficient of the target material.

[0029] Specifically, the distance power sequence is formed by setting the distance power according to M = (N+1) / 2 times the target size (i.e., the target coverage size). It is assumed that the noise level of the receiver measured when there is no target is... The entire power sequence is set according to trigonometric functions, as shown in the following formula: .

[0030] In the above embodiments, range power sequence analysis is performed on the radar signal data to obtain multiple range power sequences, which can prevent the interference signal from being detected by the radar and greatly improve the precision jamming capability.

[0031] Optionally, as an embodiment of the present invention, the radar signal data includes fast time variables, frequency modulation slope, radar signal carrier frequency, reference range, and signal pulse width; The process of calculating the interference signal from the radar signal data, the interference range sequence, the Doppler sequence, and all the range power sequences to obtain the initial airborne radar interference signal includes: The initial airborne radar jamming signal is obtained by calculating the fast time variable, the frequency modulation slope, the radar signal carrier frequency, the reference range, the signal pulse width, the jamming range sequence, the Doppler sequence, and all the range power sequences using the seventh equation. The seventh equation is: , in, , This is the initial airborne radar jamming signal. For the first The distance power sequence corresponding to each sampling point Doppler serial number, For the preset number of sequences, It is an imaginary number. Doppler sequence, It is a unit step function. For fast time variables, For reference distance, For interference range sequence, The distance dimension index, At the speed of light, For radar signal carrier frequency, For frequency modulation slope, For rectangular window functions, This represents the signal pulse width.

[0032] It should be understood that for imaging radar, LFM signals are one of the most commonly used broadband signals. Assume the radar transmits an LFM signal. It can be expressed as follows: , , Where t is a fast time variable, T is the pulse width of the signal (i.e., the signal pulse width), and f0 is the carrier frequency of the signal (i.e., the radar signal carrier frequency). For frequency modulation slope, This is a rectangular window function.

[0033] Specifically, a two-dimensional target scattering power function is designed, and a two-dimensional concealed interference waveform is constructed according to range-time and Doppler parameters. (i.e., the initial airborne radar jamming signal), the formula is as follows: , k is the index of the multiple disparity dimension (i.e., the Doppler index), and s is the index of the distance dimension (i.e., the distance index).

[0034] In the above embodiments, interference signal calculations are performed on radar signal data, interference range sequences, Doppler sequences, and all range power sequences to obtain initial airborne radar interference signals. This enables the interference signals to be undetectable by the radar, greatly improving the precision interference capability.

[0035] Optionally, as another embodiment of the present invention, addressing the problem of how to covertly interfere with existing constant false alarm rate (CFAR) detection algorithms when airborne radar is conducting important ground-based detection, the present invention designs interference in the target range and Doppler domain, changing the peak feature image of the target in the radar range Doppler domain into a typical conic function, making it difficult for CFAR detection to implement an averaging algorithm. This achieves target protection while ensuring that the interference is not detected by the radar, thereby achieving covert interference with the airborne radar target. Simulation results based on measured data verify the effectiveness of this method.

[0036] Optionally, as another embodiment of the present invention, the precise electronic warfare capability of the present invention is mainly reflected in the precise target selection and positioning capability, the precise electronic attack capability, and the precise command and control capability. Among them, the precise target selection and positioning capability is a prerequisite for precise electronic attack. By achieving precision in space-time-frequency, the energy of the jamming signal is increased, thereby achieving effective jamming of AESA radar.

[0037] Alternatively, as another embodiment of the present invention, the covert interference of the present invention can form a protective effect on the target, making it difficult for typical constant false alarm rate detection to achieve target detection, and will not make the interference signal detectable, thereby improving the accuracy of interference capability.

[0038] Alternatively, as another embodiment of the present invention, such as Figures 2 to 6 As shown, this invention uses measured data from an airborne MCARM early warning aircraft radar to verify the performance of the intermittent reconfiguration jamming method within the STAP radar of an early warning aircraft. The data has a pulse repetition frequency of 984 Hz, uses 630 range gates, has 11 antennas, and the angle between the array surface and the velocity is 7.28 degrees. In the experiment, only 11 array elements and all 128 coherently processed pulses were used. Figure 5 As shown, MCARM data exhibits very clear strong and weak clutter partitions, and there are numerous moving targets outside the main clutter band. The commonly used 3-DT space-time adaptive processing method is employed for clutter suppression. This method achieves good clutter suppression while reducing the computational load of space-time adaptive processing. After space-time adaptive processing, clutter in the entire region is well suppressed, and some moving targets can be clearly seen in the Doppler open area outside the main clutter band.

[0039] like Figure 3 and 4 As shown, after pulse compression, the target in this image forms a relatively sharp peak in the Doppler 19 channel, which is close to the 9th channel, thus allowing for good detection using constant false alarm rate (CFAR) detection. From... Figure 5 As can be seen, the target's peak values ​​exhibit a typical trigonometric function shape. However, due to the lack of typical Sink's function peak characteristics after pulse compression, the CA constant false alarm rate (CFAR) detection method is insufficient for target detection. Figure 6 As can be seen from the Doppler 19 channel, the target in the 9 channel is concealed from the radar and is difficult to detect and interfere with.
