Description

Technical Field

[0001] The embodiments of the present specification relate to the field of communication technology, and in particular to an anti-deceptive interference signal suppression method. Background Art

[0002] Frequency hopping signal is an advanced communication technology that uses spread spectrum and frequency hopping technology and has extremely strong anti-interference and communication security performance.

[0003] In actual application environments, active interference is the most common form of interference. Active interference can be divided into suppression interference and deception interference. Suppression interference refers to interference formed by transmitting high-power noise or other signals, which seriously reduces the signal-to-noise ratio of the receiving end of the enemy's electronic equipment, seriously damages the information, or completely submerges the useful signal in the interference. Deception interference is a kind of interference that artificially transmits and forwards electromagnetic wave signals to make the interference similar to the target signal in order to disrupt or deceive the enemy's electronic equipment and cause the enemy to receive wrong information. Suppression interference includes broadband interference, pulse interference, narrowband targeting interference, audio interference, sweep frequency interference, etc. Deception interference includes generative interference and forwarding interference.

[0004] Forwarding interference is to directly amplify and forward the real signal received by its own antenna after signal delay, or store a section of signal and forward it periodically, so that the target receiver can capture a false signal. Direct forwarding signals can be captured and demodulated normally, but the forwarding delay causes ranging errors. After normal capture and demodulation of stored signals, there are also ranging errors, and due to discontinuous data, the demodulation will lose lock, recapture, and then lose lock again. Forwarding interference is technically easy to implement, but has poor flexibility and controllability, but it is simple to implement and has low cost.

[0005] Generative jamming requires cracking the way the real signal is generated, and then autonomously generating jamming signals with the same structure to achieve information deception. This jamming technology is complex and difficult to implement.

[0006] Since deceptive jamming has the same structure as real signals, it is more difficult to identify and suppress than other jamming. Therefore, a better solution is urgently needed. Summary of the invention

These terms are only used to distinguish the same type of information from each other.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0053] In this specification, a method for suppressing an anti-deceptive interference signal is provided. This specification also relates to an anti-deceptive interference signal suppression device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0054] See also Figure 1 , Figure 1 A flowchart of an anti-deceptive interference signal suppression method provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0055] Step 101: Capture a strong signal and determine a strong signal capture result.

[0056] In practical applications, see Figure 2 First, a strong signal is captured. A strong signal may be an interference signal or a real signal. A signal with a signal-to-noise ratio greater than 15 dB is called a strong signal, and a signal with a signal-to-noise ratio greater than 15 dB is called a weak signal. If a strong signal is not captured, step 102 is performed.

[0057] In a possible implementation, it also includes: when the strong signal capture result is completion of capture, determining the number of strong signal peaks, and when the number of strong signal peaks reaches a preset number, determining the order of strong signal peaks; determining the real signal based on the order of strong signal peaks, tracking the real signal, and determining the initial signal; filtering out interference on the initial signal to determine the target signal.

[0058] In practical applications, if there is a strong signal and the number of peaks is 2, the interference and the real signal are judged according to the order of the peaks, and then the real signal is tracked.

[0059] In a possible implementation, it also includes: when the number of strong signal peaks is 1, frequency domain notching is performed on the strong signal according to the frequency hopping rule to determine the signal to be detected; weak signal detection is performed on the signal to be detected to determine the weak signal detection result; when the weak signal detection result is that the capture is completed, the real signal is determined according to the order of the weak signal and the strong signal, the real signal is tracked to determine the initial signal; interference filtering is performed on the initial signal to determine the target signal.

[0060] In practical applications, if there is a strong signal (which may be interference or signal) and the number of peaks is 1, then according to the frequency hopping rule, the frequency hopping frequency where the strong signal is located is notched in the frequency domain (when a strong interference signal exists, it may not be possible to capture a weak signal, so it is necessary to notch the strong signal in the frequency domain), and then perform weak signal detection. If the weak signal is not captured, the strong signal is the real signal, and the strong signal is tracked; if the weak signal is captured, the interference and the real signal are judged according to the order in which the strong signal and the weak signal arrive in time, and then the real signal is tracked. In the tracking stage, the down-converted signal is low-pass filtered to filter out deceptive interference with a forwarding delay greater than 1 hop.

[0061] Step 102: Capture the weak signal based on the strong signal capture result to determine the weak signal capture result.

[0062] In a possible implementation, capturing a weak signal based on a strong signal capture result to determine a weak signal capture result includes: if a strong signal capture result does not exist, capturing a weak signal to determine a weak signal capture result.

[0063] In practical applications, see Figure 2 If there is no strong signal, weak signal capture is performed. If a weak signal is captured, step 103 is performed. If a weak signal is not captured, step 101 is performed.

[0064] Step 103: Determine the number of weak signal peaks based on the weak signal capture result, and determine the order of the weak signal peaks when the number of weak signal peaks reaches a preset number.

[0065] In a possible implementation manner, determining the number of weak signal peaks based on the weak signal capture result further includes: when the weak signal capture result is capture completion, determining the number of weak signal peaks.

[0066] In practical applications, see Figure 2 If the weak signal is captured, the number of weak signal peaks is determined.

[0067] In a possible implementation, when the number of weak signal peaks reaches a preset number, determining the order of weak signal peaks includes: when the number of weak signal peaks is 2, determining the order of weak signal peaks.

[0068] In practical applications, if the number of peak values ​​of captured weak signals is 2, step 104 is executed to determine interference and real signals according to the order of peak values, and then the real signal is tracked.

[0069] In a possible implementation, the method further includes: when the number of weak signal peaks is 1, tracking the weak signal to determine an initial signal; and filtering interference on the initial signal to determine a target signal.

[0070] In practical applications, if the number of peak values ​​of captured weak signals is 1, it will directly switch to tracking.

[0071] Step 104: Determine the real signal based on the weak signal peak sequence, track the real signal, and determine the initial signal.

[0072] In practical applications, see Figure 3 The code loop adopts narrow correlation technology to prevent the code tracking loop from being pulled by strong interference signals or falsely locked.

[0073] Specifically, in the code tracking loop of the spread hop signal, a delay lock loop is generally used. The delay lock loop uses the correlation of the code to locally generate leading and lagging code signals that are respectively correlated with the received signal, and obtain the code tracking error after subtraction, so as to adjust the loop and realize code tracking. The spacing between the leading and lagging code signals is generally the length of the code chip, which can take into account both the code tracking range and the code tracking performance. When there is deceptive interference, the deceptive interference will cause the delay lock loop phase detection curve to be distorted, which may extract the wrong code tracking error, and even make the code tracking loop gradually converge to the deceptive interference. Therefore, in order to reduce the traction of deceptive interference on the code tracking loop, a narrow correlation technology is used, that is, the spacing between the leading and lagging code signals is less than the code chip length (such as 1 / 2 code chip or 1 / 4 code chip), which can sacrifice part of the capture range, but can improve the code loop tracking performance and prevent being pulled by deceptive interference. Since the capture range of narrow correlation technology is reduced, when switching from capture to tracking, the conventional code loop can be used first to complete the tracking of the signal capture residual and reduce the uncertainty range of the code, and then switch to the narrow correlation code loop to reduce the impact of deceptive interference on the code tracking loop.

[0074] Step 105: Filter out interference on the initial signal and determine the target signal.

[0075] In practical applications, see Figure 4 According to the location of the ground station and the satellite orbit, the Doppler, Doppler change rate and distance of the received signal can be calculated in real time. By distinguishing the Doppler, Doppler change rate and measured pseudo-range output from the demodulated signal, deception interference identification can be realized.

[0076] Specifically, in the spread-hop system, the receiver needs to complete signal capture, de-hopping, de-spreading, carrier tracking, code tracking, frame synchronization, decoding and other processing. Among them, signal capture may capture deceptive interference, so that the receiver tracks the deceptive interference; on the other hand, since the deceptive interference power is very strong, it may also cause the code tracking loop of the receiver to be pulled by the deceptive interference signal during the normal tracking process, and gradually converge to the deceptive interference. Both methods will cause the receiving end to obtain wrong information.

[0077] Considering that the jammer system that generates the deceptive jammer is in a different position from the real target and has a different movement speed, the deceptive jammer can be identified from the perspective of distance and Doppler.

[0078] Doppler and Doppler rate of change identification: Since the target is a cooperative target, the receiver generally knows the target's position and velocity information. Combined with its own position and velocity, it can predict the Doppler and Doppler rate of change. Assume that the position vectors of itself and the target in the reference system are , the velocity vectors are , then the difference between the position vector and the velocity vector is:

[0079]

[0080] The Doppler calculation is:

[0081]

[0082] in, is the normalized position vector, is the carrier frequency, is the speed of light, is the signal wavelength.

[0083] Based on the Dopplers calculated multiple times, the Doppler change rate can be calculated.

[0084] In the carrier tracking loop of the receiver, the Doppler and Doppler change rate of the signal can be tracked in real time. The tracked signal Doppler and Doppler change rate are compared with the predicted Doppler and Doppler change rate. When the error exceeds the threshold, it can be considered that the tracked target is not the real target. At this time, the tracking is terminated and the target is recaptured.

[0085] Distance increment recognition: Based on the position vectors of the self and the target, the distance between the two can be calculated:

[0086]

[0087] Among them, the position vector

[0088] In the ranging module of the receiver, the pseudorange of the distance to the target is calculated. Since the pseudorange includes the real distance to the target and the distance difference caused by the transmission and reception delay, the pseudorange is not equal to the target distance. However, the change in the pseudorange is consistent with the change in the target distance. Therefore, the increment of the satellite-to-ground distance is calculated by the satellite-to-ground distance, and the increment of the pseudorange is calculated by the pseudorange. When the error between the two increments exceeds the threshold, it can be considered that the tracked target is not the real target. At this time, the tracking is terminated and the target is recaptured.

[0089] In addition, when recapture the target, the Doppler prediction and distance prediction information can be used to capture targets with similar Doppler and distance, thereby preventing the capture of the wrong target.
