Description

Technical Field

[0001] This invention relates to the field of radar jamming, and in particular to a method and related components for achieving radar jamming. Background Technology

[0002] With the advancement of electronic technology, the functional requirements for radar have become increasingly complex. In the military field, the jamming function of radar has become a key requirement. Radar jamming refers to the ability of a radar to intercept signals transmitted from an adversary radar. Because these signals can spread throughout the surrounding space, our radar can also receive them. Therefore, our radar modifies the transmitted signal to generate a jamming signal and sends it to the target radar. This causes the target radar to receive many similar signals, making it impossible to distinguish the correct signal. The jamming function of a radar is closely related to the jamming capability of its generated jamming signal; therefore, improving the jamming capability of the radar's generated jamming signal is crucial. Summary of the Invention

[0003] The purpose of this invention is to provide a method and related components for achieving radar jamming, which can improve the performance of radar deception and jamming.

[0004] To solve the above-mentioned technical problems, the present invention provides a method for achieving radar jamming, comprising:

Each sample signal includes N bits of binary code, and each sample signal in the sampling matrix is ​​different from the others. M and N are both positive integers.

[0006] The sample signal with the strongest interference among all the sample signals is taken as the interference signal;

[0007] The jamming signal is sent to the enemy radar.

[0008] Preferably, after acquiring the M raw signals emitted by the opponent's radar, the process further includes:

[0009] The relevant information of the opposing radar is determined based on the frequency of the original signal, wherein the relevant information includes the azimuth, altitude and distance of the opposing radar.

[0010] Preferably, the M raw signals transmitted by the opponent's radar are acquired, including:

[0011] The original signal emitted by the opposing radar is acquired once at a preset time interval until M original signals are acquired. The preset time intervals for two consecutive acquisitions are different, and the lengths of the M original signals are all the same.

[0012] Preferably, M sample signals are generated by sampling the M original signals using the M sample signals in the sampling matrix, including:

[0013] For any of the original signals, the following steps are performed:

[0014] The N bits of the binary code included in the sampled signal corresponding to the original signal are read sequentially. When the binary code is 0, the original signal is sampled to obtain a sub-sampled signal. When the binary code is 1, the newly obtained sub-sampled signal is sent.

[0015] The received sub-sample signals are combined to obtain the sample signal.

[0016] Preferably, the signal with the strongest interference performance among all the sample signals is used as the interference signal, including:

[0017] The deceptive score of each sample signal is determined using the fitness function in a genetic algorithm;

[0018] The sample signal with the highest deception score is used as the interference signal.

[0020] Determine the M / 2 sample signals with the highest interference intensity from each of the sample signals;

[0021] The process involves performing a multiplication operation on each of the optimized sample signals to obtain M new sample signals, and then proceeding to the step of determining the M / 2 optimized sample signals with the highest interference intensity among the sample signals.

[0022] After the number of breeding operations reaches a preset number, the step proceeds to the step of using the sample signal with the strongest interference among the sample signals as the interference signal.

[0023] Preferably, a multiplication operation is performed on each of the optimized sample signals to obtain M new sample signals, including...

[0035] In summary, this application discloses a method and related components for radar jamming. First, after acquiring the original signal transmitted by the opposing radar, each original signal is sampled using a sampling matrix. Since the binary codes included in each sampling signal in the sampling matrix are different, the sample signals generated using these sampling signals are also different, thus each sample signal has strong deception and jamming capabilities. Furthermore, the sample signal with the strongest jamming power is used as the final jamming signal transmitted to the opposing radar, further improving the radar's jamming performance.

[0040] The core of this invention is to provide a method and related components for achieving radar jamming, which can improve the performance of radar deception and jamming.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please refer to Figure 1 , Figure 1 A flowchart of a method for achieving radar jamming provided by the present invention, the method comprising:

[0043] S1: After acquiring M raw signals emitted by the enemy radar, M sample signals are generated by sampling the M raw signals using the M sample signals in the sampling matrix. Each sample signal includes N bits of binary code, and each sample signal in the sampling matrix is ​​different from the others. M and N are both positive integers.

[0044] S2: Select the sample signal with the strongest interference among all sample signals as the interference signal;

[0045] S3: Send jamming signals to the enemy radar.

[0046] The primary method of radar jamming is to sample the original signal emitted by the opposing radar, modulate it to create a jamming signal similar to the original signal, and then interfere with other devices that need to receive the original signal from the opposing radar. To improve the deception and jamming performance of radar, the jamming performance of the jamming signal sent by the radar to the opposing radar needs to be enhanced.

[0047] Therefore, this application first acquires M raw signals transmitted by the opposing radar to generate jamming signals based on the raw signals. The time interval between acquiring the raw signals transmitted by the opposing radar is a preset time interval. When the preset time interval between two consecutive acquisitions of raw signals is equal, it is uniform sampling. However, the jamming deception of this sampling method is relatively weak. Therefore, in this application, the preset time interval between two consecutive acquisitions of raw signals can be set to different lengths. That is to say, the preset time interval in this application can be changed. This application does not make a special limitation on the specific length of the preset time interval. However, for the simplicity of the subsequent process of modulating and generating sample signals based on the raw signals, it is necessary to ensure that the length of the raw signals acquired each time is the same.

[0048] After acquiring M raw signals transmitted by the opponent's radar, the raw signals are sampled and modulated using the sampling signals in the sampling matrix. To improve the deception and jamming performance of each sample signal, the sampling signals included in the sampling matrix in this application are all distinct from each other. Specifically, the processor can randomly generate M sampling signals containing N-bit binary codes. After confirming that each sampling signal is distinct, they can be assembled into a sampling matrix. The raw signals correspond one-to-one with the sampling signals in the sampling matrix; therefore, the number of rows in the sampling matrix is ​​the same as the number of raw signals. The number of columns in the sampling matrix, i.e., the number of binary codes included in each sampling signal, can be set according to actual conditions, and this application does not impose any special limitations on this. Since the sampling signals in the sampling matrix are all distinct from each other, the sample signals generated by each raw signal using its corresponding sampling signal are also distinct, which improves the radar's deception and jamming performance.

[0049] The specific process of obtaining a sample signal using the sampled signal and the original signal is as follows: The binary code of each bit of the sampled signal corresponding to the original signal is read sequentially. In the binary code, 0 represents sampling and 1 represents transmission. For example, if the sampled signal is 010100110000101111, the first four bits (0101) indicate that the original signal is sampled once and then the sampled signal is transmitted; 0011 indicates that the signal is sampled twice and transmitted twice, but both transmitted signals are the signal obtained from the second 0 sample; 00001 indicates that the signal is sampled four times consecutively and then the signal obtained from the fourth sample is transmitted; 01111 indicates that the signal is sampled once and then transmitted four times. Finally, the various signals to be transmitted are combined and concatenated to generate the final sample signal.

[0050] It should also be noted that each sampled signal includes N bits of binary code. In practical applications, the correspondence between 1 and 0 and sampling and transmission can be customized. This application does not impose any special restrictions on this.

[0051] After obtaining M sample signals, this application does not directly send each sample signal to the opponent's radar. Instead, it further determines the sample signal with the strongest interference among all sample signals as the final interference signal sent to the opponent's radar, thereby further improving the radar's interference performance. Specifically, the fitness function in a genetic algorithm can be used to calculate the deception score of each sample signal, and then the sample signal with the highest deception score is used as the interference signal, further improving the radar's interference performance. It should be noted that this application does not impose any particular limitation on the fitness function used and can choose it according to the actual situation.

[0052] In summary, this application discloses a method for achieving radar jamming. First, after acquiring the original signal transmitted by the opponent's radar, each original signal is sampled using each sample signal in the sampling matrix. Since the binary codes included in each sample signal in the sampling matrix are different, the sample signals generated using the sample signals are also different, thus each sample signal has strong deception and jamming capabilities. Furthermore, the sample signal with the strongest jamming capability among all sample signals is used as the final jamming signal transmitted to the opponent's radar, further improving the radar's jamming performance.

[0053] Based on the above embodiments:

[0054] As a preferred embodiment, after acquiring the M raw signals transmitted by the opponent's radar, the method further includes:

[0055] The relevant information of the enemy radar is determined based on the frequency of the original signal. This information includes the enemy radar's azimuth, altitude, and distance.

[0056] First, radar signals are generally linear frequency modulated (LFM) signals. The frequency of an LFM signal gradually increases over time. Therefore, the azimuth and other relevant information of the transmitting radar can be determined based on the frequency of the received LFM signal. Based on this principle, in this embodiment, after acquiring M raw signals transmitted by the opposing radar, the azimuth, altitude, and range information of the opposing radar are determined based on the frequencies of the raw signals. This achieves radar detection functionality in addition to radar jamming, realizing integrated radar jamming and detection.

[0057] As a preferred embodiment, before using the most disruptive sample signal among the various sample signals as the interference signal, the method further includes:

[0058] Identify the M / 2 optimal signals from each sample signal with the highest interference intensity;

[0059] The optimization signal of each sample is multiplied to obtain M new sample signals, and then the process proceeds to determine the M / 2 sample optimization signals with the highest interference intensity among the sample signals.

[0060] After the number of breeding operations reaches a preset number, the step proceeds to use the sample signal with the strongest interference among all sample signals as the interference signal.

[0061] To further enhance radar jamming performance, this embodiment introduces a breeding operation from a genetic algorithm to improve the deception jamming performance of the final jamming signal sent to the enemy radar. First, the top M / 2 sample signals with the highest jamming strength are determined from M sample signals. Specifically, they can be sorted using a deception score calculated by an fitness function; this application does not impose any particular limitation on this. The bottom M / 2 sample signals with the lowest jamming strength are discarded, retaining only the top M / 2 sample signals with the highest jamming strength. A breeding operation is then performed on each of these optimized sample signals to obtain M new sample signals. The jamming performance of these M new sample signals is significantly improved compared to the initial M sample signals. The above process is repeated for the newly obtained M sample signals. The number of iterations, i.e., a preset number, is set according to actual needs. After the preset number of breeding operations is reached, the sample signal with the strongest jamming performance from the latest sample signals is selected as the jamming signal, thereby greatly improving the radar jamming capability.

[0062] In summary, the introduction of a genetic algorithm in this embodiment can save a lot of computation required to select the optimal interference signal. In the entire selection process, only signals with relatively poor interference need to be rejected, which can also improve the efficiency of radar in performing interference functions.

[0063] As a preferred embodiment, a multiplication operation is performed on each optimized sample signal to obtain M new sample signals, including

[0064] The optimization signals of each sample are sequentially swapped at a single point or at two points, or the two optimization signals of the M / 4 sample signal combinations are sequentially crossed uniformly or arithmetically, and the optimization numbers of each sample signal combination are all different.

[0065] The M / 2 sampled signals after the swap are used as the breeding sampled signals;

[0066] The M / 2 breeding sampling signals and the M / 2 sample optimization signals are used as M new sample signals.

[0067] This embodiment provides four methods for performing the breeding operation. One method, using a single sample optimization signal as the breeding subject, involves single-point or two-point swapping of the single sample optimization signal, which is relatively simple. For example, if the sample optimization signal is 01010011-0000101111, a single-point swap uses the middle hyphen (-) as the dividing point, resulting in 0000101111-01010011. A two-point swap uses the two middle hyphens (-) as the dividing points, resulting in 0011-0000101111-0101. Another method involves uniformly or arithmetically crossing two sample optimization signals in the sample signal combination. Uniform crossing involves randomly swapping each bit in the two sample optimization signals, while arithmetic crossing involves linearly calculating the two sample optimization signals to obtain two new sample optimization signals. The specific method can be set according to the actual situation.

[0068] In summary, this embodiment obtains more sample signals by performing a multiplication operation on the sample optimization signal, so as to select the jamming signal with the strongest jamming performance and improve the jamming performance of the radar.

Since the binary codes included in each sampling signal in the sampling matrix are different, the sample signals generated using these sampling signals are also different, thus each sample signal has strong deception and jamming capabilities.
