Description

Technical Field

[0001] The invention belongs to the technical field of radar anti-interference, and relates to a radar anti-interference method based on Stackelberg game. Background Art

[0002] Radar is a device that can work all day and all night, regardless of day or night, and is not blocked by fog, clouds, or rain. Radar uses the scattering of electromagnetic waves by targets to detect targets and obtain information such as their distance, speed, and angle. It is an important sensor for detecting and identifying targets and guiding weapons to complete attack missions. When detecting non-cooperative targets, radar may suffer from various active / passive interference, and corresponding anti-interference measures need to be taken to win the electromagnetic spectrum war. In electromagnetic spectrum warfare, radar needs to study interference perception, interference pattern recognition, and corresponding anti-interference measures, as well as methods for reasonably applying these anti-interference measures throughout the game between radar and jammer.

[0003] Since the confrontation between radar and jammers is a dynamic process, for adaptive and intelligent jammers, the jamming tactics and waveform patterns are not static during an attack and defense confrontation. If a certain jammer is successfully suppressed by the radar system and fails to work, the jammer will switch to other jamming patterns. Therefore, even if the radar implements anti-jamming measures and gains an advantage in a certain round, it does not mean that it will be able to carry out the mission and win the final victory.

[0004] In the conventional method of radar countering jammers, the jamming behavior is not predicted and the countermeasure cannot be taken first. Only when the jammer is found, an anti-jamming measure is selected to restrain it, which is in a passive response situation. When there are multiple anti-jamming measures to choose from in the face of current interference, the measure with the greatest current benefit is selected, without fully considering the continuity and dynamics of the radar and the jammer, and without taking into account the final winning conditions of the radar to adopt the corresponding anti-jamming method. Summary of the invention

[0005] The purpose of the present invention is to address the scenario where conventional radar anti-interference methods do not predict interference measures. There are 1) passive response to interference, no prediction of interference behavior, and anti-interference measures are taken only after the radar is interfered, which cannot take the initiative and is always passive; 2) when selecting anti-interference measures, only current benefits are considered without considering the long-term benefits of the radar, and insufficient consideration is given to the final winning conditions. A radar anti-interference method based on Stackelberg game is proposed.

[0006] In order to achieve the above object, the present invention adopts the following technical scheme.

[0007] The radar anti-interference method relies on a radar anti-interference system, including an interference identification module, an anti-interference measure selection module, an interference type prediction module, an interference benefit pre-determination module, an anti-interference measure selection module, an interference type control module, a timing module and a win-lose determination module;

[0008] The interference identification module is connected to the anti-interference measure selection module, the anti-interference measure selection module is connected to the interference type prediction module, the interference type prediction module is connected to the interference benefit pre-determination module, the interference benefit pre-determination module is connected to the anti-interference measure selection module, the anti-interference measure selection module is connected to the interference type control module, the interference type control module is connected to the timing module; the timing module is connected to the victory and defeat determination module;

[0009] The interference identification module identifies the interference to the radar at a certain recognition rate and determines the type of interference;

[0010] The anti-interference measure selection module selects an anti-interference measure that can restrain the current interference type from all anti-interference measures as a candidate behavior of the radar according to the interference type currently faced by the radar;

[0011] The anti-interference measure selection module selects the best anti-interference measure from all radar subsequent candidate behaviors;

[0012] The interference type prediction module predicts subsequent interference behaviors based on the Stackelberg game to determine the interference type that the jammer may choose if the radar adopts a certain candidate behavior;

[0013] The interference benefit pre-determination module determines the maximum benefit interference type of the jammer for each subsequent candidate behavior of the radar;

[0014] The interference type control module selects the next interference type after the jammer determines the radar anti-interference measures;

[0015] The timing module calculates the time required for the interference behavior to take effect, the time required for the radar to identify the interference, the time required for the radar anti-interference measures, the time required for the jammer to identify the radar measures, and updates the remaining game time as the game progresses;

[0016] The winning and losing determination module determines whether the radar has completed anti-interference when the remaining game time is just reduced to zero. When the remaining game time is zero, there are two situations:

[0017] 1) If the radar anti-interference measures take effect and the jammer's interference does not take effect, the radar completes the anti-interference;

[0018] 2) If the jammer's interference is effective and the radar's anti-interference measures are not effective, the radar has not completed anti-interference;

[0019] If the remaining game time is greater than zero, the interference identification module, the anti-interference measures selection module, the interference type prediction module, the interference benefit pre-determination module, the anti-interference measures selection module, the interference type control module, the timing module and the winning and losing determination module will continue to be executed;

[0020] The method comprises the following steps:

[0021] S1, parameter setting;

[0022] The parameters are parameters set by prior information and do not change after the interference type and anti-interference measure type are determined. Specifically, they include: the time required for the current round of interference behavior to take effect, the time required for the radar to identify the interference, the time required for the radar anti-interference measures, and the time required for the jammer to identify the radar measures;

[0023] S2, the interference identification module identifies the current interference type;

[0024] S3, the anti-interference measure selection module selects radar candidate behaviors;

[0025] S4, the jammer type prediction module determines the jammer type that the jammer may select if the radar adopts a candidate action;

[0026] S5, the jamming benefit pre-determination module determines the jamming type when the jammer obtains the maximum benefit for the candidate radar behavior;

[0027] S6, the anti-interference measure selection module selects the optimal anti-interference measure from all radar subsequent candidate behaviors;

[0028] S7, the interference type control module selects the next interference type after the jammer determines the radar anti-interference measures;

[0029] S8, the timing module calculates the time consumed in the game process and updates the remaining game time;

[0030] The time consumed in the game process includes: the time for the interference recognition module to recognize the current interference type, the effective time of the radar anti-interference measures, the time for the jammer to recognize the anti-interference measures, and the effective time of the jammer interference type;

[0031] The remaining game time is equal to the set initial remaining game time minus the game process consumption time;

[0032] S9, the winning and losing determination module determines whether the game is over and whether the radar has completed anti-interference at the end of the game. If so, the radar anti-interference result is output, otherwise, jump to S2;

[0033] Determining whether the game is over is specifically: determining whether the remaining game time is negative, if it is negative, the game and timing are over; otherwise, it indicates that the game is not over and jumps to S2;

[0034] Anti-interference effect evaluation: evaluate whether the anti-interference measures have played a role;

[0035] If the anti-interference effect is good, the radar's recognition rate for this type of interference can be improved.

[0036] If the anti-interference effect is not good, the radar's recognition rate for this type of interference can be reduced.

[0037] The method of improving the recognition rate of the radar for this type of interference includes a single-step adjustment coefficient and an upper limit of the adjustment coefficient, and the upper limit of the adjustment coefficient must be less than 100%;

[0038] The method of reducing the recognition rate of the radar to the interference of this type includes a single-step adjustment coefficient and a lower limit of the adjustment coefficient;

[0039] When the interference identification module starts working, it is necessary to set parameter values ​​for the remaining game time, and set the radar's recognition probability and recognition time for various interference types, the effective time of all radar anti-interference measures, the jammer's recognition time for radar measures, and the effective time of various interference types of the jammer.

[0040] In the embodiment of the present invention, the radar predicts the interference type implemented by the jammer based on the Stackelberg game, and takes anti-interference measures in advance to restrain the interference type that is about to take effect. Through interference type identification, radar anti-interference behavior selection, interference type prediction, interference benefit pre-determination, anti-interference measure selection, and interference type control, the anti-interference measure selection of the jammer is continuously made in the dynamic game. Through the anti-interference method based on the Stackelberg game, the prior information in the confrontation between the radar and the jammer can be fully utilized, the initiative can be seized, the passive can be turned into the active, the radar behavior logic can be changed, and interference restraint can be implemented based on interference prediction. This method can be applicable to the confrontation scenes between radars and jammers in the air, at sea, and on land, and has a wide range of applications and good promotion prospects.

[0042] The radar anti-interference method based on Stackelberg game proposed in the present invention has the following beneficial effects compared with the existing radar anti-interference method:

[0043] 1. The method changes the radar anti-interference measure selection logic and implements interference countermeasures based on interference prediction. After identifying interference, the best anti-interference measure can be selected from a number of alternative anti-interference measures, so that it can restrain the next round of interference types and always take the lead in confrontation;

[0044] 2. The method can be applied to the confrontation scenarios between radars and jammers in the air, at sea, and on land, and has a wide range of applications and good promotion prospects. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] In order to achieve radar anti-interference, the embodiment of the present disclosure provides a radar anti-interference method based on Stackelberg game. The following is a detailed description of each of the embodiments provided by the present invention in conjunction with the accompanying drawings.

[0054] Example 1

[0055] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the embodiment of the present invention provides a radar anti-interference method based on Stackelberg game, including radar anti-interference measure selection, radar anti-interference method timing and other links. Figure 1 It can be seen that the radar anti-interference method includes the following steps:

[0056] Step 1: The interference recognition module recognizes the interference to the radar at a certain recognition rate and determines the interference type;

[0057] The specific implementation of this step corresponds to S2 in the invention content;

[0058] Step 2: The anti-interference measure selection module selects the anti-interference measures that can overcome the current interference type from all anti-interference measures as candidate radar behaviors according to the interference type currently faced by the radar;

[0059] The specific implementation of this step corresponds to S3 in the invention content;

[0060] Step 3: The interference type prediction module predicts the subsequent interference behavior based on the Stackelberg game to determine the interference type that the jammer may choose if the radar takes a certain candidate behavior;

[0061] The specific implementation of this step corresponds to S4 in the invention content;

[0062] Step 4: The jammer benefit pre-determination module determines the jammer's maximum benefit jammer type for each radar subsequent candidate behavior;

[0063] The specific implementation of this step corresponds to S5 in the invention content;

[0064] Step 5: The anti-interference measure selection module selects the optimal anti-interference measure from all radar subsequent candidate behaviors;

[0065] The specific implementation of this step corresponds to S6 in the invention content;

[0066] Step 6: After the jammer determines the radar anti-jamming measures, the jammer type control module selects the next jamming type.

[0067] The specific implementation of this step corresponds to S7 in the invention content;

[0068] Step 7: The timing module calculates the time consumed by the game process and updates the remaining game time. Specifically, the timing module calculates the time required for the interference behavior to take effect, the time required for the radar to identify the interference, the time required for the radar to take anti-interference measures,

[0069] The time required for the jammer to identify the radar measures and update the remaining game time as the game progresses;

[0070] The specific implementation of this step corresponds to S8 in the invention content;

[0071] The time consumed in the game process includes: the time for the interference recognition module to recognize the current interference type, the effective time of the radar anti-interference measures, the time for the jammer to recognize the anti-interference measures, and the effective time of the jammer interference type;

[0072] The remaining game time is equal to the set initial remaining game time minus the game process consumption time;

[0073] Step 8: The winning and losing determination module determines whether the radar has completed anti-interference when the remaining game time is reduced to zero;

[0074] If the game is over, the application result of this radar anti-interference method is output;

[0075] The specific implementation of this step corresponds to S9 in the invention content;

[0076] The winning and losing determination module determines whether the radar has completed anti-interference when the remaining game time is just reduced to zero. When the remaining game time is zero, there are two situations:

[0077] 1) If the radar anti-interference measures take effect and the jammer's interference does not take effect, the radar completes the anti-interference;

[0078] 2) If the jammer's interference is effective and the radar's anti-interference measures are not effective, the radar has not completed anti-interference;

[0079] If the remaining game time is greater than zero, it means the game is not over yet and jump to step 1 to continue;

[0080] It should be noted that the radar anti-interference measure selection process corresponds to steps 1 to 5, such as Figure 2 As shown, based on the radar's recognition result of the interference type, the jammer's countermeasures are predicted for each candidate action of the radar and the radar anti-interference measure with the greatest benefit is selected.

[0081] The timing module process that the radar anti-interference method relies on is as follows: Figure 3As shown, according to the initial remaining game time, after each radar takes anti-interference measures, the time required for the current round of interference behavior to take effect, the time required for the radar to identify the interference, the time required for the radar to take anti-interference measures, and the time required for the jammer to identify the radar measures are subtracted, and the remaining game is updated.

[0082] Time, including the following steps:

[0083] Step 1, initialize the game time;

[0084] Step 2: Time the game process to get the game process time, specifically:

[0085] The game process time includes the time for the interference recognition module to identify the current interference type, the time for calculating the effectiveness of the radar anti-interference measures, the time for the jammer to identify the anti-interference measures, and the time for the jammer interference type to take effect;

[0086] Step 3. Determine whether the remaining game time is negative. If so, the game and timing are over; otherwise, update the game time and jump to Step 2 to continue timing the game process.

[0087] The remaining game time, i.e., the current remaining game time, is equal to the game time minus the game process time;

[0088] The updating of the game time is to assign the current remaining game time to the game time.

[0089] The radar anti-interference measures, interference types and other information are determined based on a priori information obtained from long-term confrontation research between radar and jammer.

[0090] The remaining game time refers to the time length from the current moment of the radar to the end of the game between the radar and the jammer. The initial remaining game time refers to the time length from the start of the radar to the end of the game between the radar and the jammer.

[0091] The conditions for determining the end of the game time between the radar and the jammer include the radar-guided missile reaching the target's no-escape zone, the radar-guided missile hitting the target, the radar losing the target and switching to search mode and subsequently failing to capture the target, etc.

[0092] The radar's interference recognition time refers to the length of time it takes for the radar to receive an interference signal and determine that it is interfering with the radar.

[0093] The effective time of the radar anti-interference measure refers to the length of time required from the radar starting to take anti-interference measures to the time the measures overcome the interference.

[0094] The jammer's recognition time for radar measures refers to the length of time it takes for the jammer to receive radar signals and extract their behavioral characteristics.

[0095] The effective time of the interference behavior refers to the length of time required for the jammer to start taking interference measures and for the measures to successfully interfere with the radar.

[0096] It should be noted that this anti-interference method does not take clutter, noise and other factors into account, and only considers the behaviors that can be controlled by radar and interference.

[0097] In the embodiment of the present invention, the radar predicts the interference type implemented by the jammer based on the Stackelberg game, and takes anti-interference measures in advance to restrain the interference type that is about to take effect. Through interference type identification, radar anti-interference behavior selection, interference type prediction, interference benefit pre-determination, anti-interference measure selection, and interference type control, the anti-interference measure selection of the jammer is continuously made in the dynamic game. Through the anti-interference method based on the Stackelberg game, the prior information in the confrontation between the radar and the jammer can be fully utilized, the initiative can be seized, the passive can be turned into the active, the radar behavior logic can be changed, and interference restraint can be implemented based on interference prediction. This method can be applicable to the confrontation scenes between radars and jammers in the air, at sea, and on land, and has a wide range of applications and good promotion prospects.

[0098] In some embodiments, the process of selecting anti-interference measures is carried out according to the following steps.

[0099] Figure 2 In the radar anti-interference measure selection flow chart shown, the interference identification module first identifies the type of interference currently suffered by the radar and gives the specific interference type.

[0100] The anti-interference measure selection module selects anti-interference measures that can overcome this interference type from all anti-interference measures that the radar can take to form candidate radar behaviors.

[0101] For each candidate radar behavior, the interference type pre-evaluation module selects the interference type that can restrain this candidate radar behavior from all the possible interference types as the candidate measure of the jammer.

[0102] For each candidate radar behavior, the jammer benefit pre-determination module selects the jammer type that can restrain the candidate radar behavior and maximize the jammer benefit from the candidate measures of the jammer.

[0103] The anti-interference measure selection module finds the anti-interference behavior that maximizes the radar benefit from all the pairs of radar candidate behaviors and jammer type with the maximum benefit, and uses this behavior as the anti-interference behavior actually taken by the radar.

[0104] Identify the current interference type, recorded as J C ;

[0105] Among the radar's optional anti-jamming measures, find the J C All measures, the number is recorded as N(J C ) types, the number of each anti-interference measure is

[0106] For each anti-jam measure, find the type of jammer that can overcome it to get the most benefit for the jammer.

[0107] Record the corresponding radar gain at this time

[0108] Find out the maximum value that the radar can obtain among all the benefits, and use this anti-interference measure as the anti-interference measure selected by the radar.

[0109]

[0110] In some embodiments, the updating process of the remaining game time includes: subtracting the time required for the current round of interference behavior to take effect, the time required for the radar to identify the interference, the time required for the radar anti-interference measures, and the time required for the jammer to identify the radar measures from the current remaining game time, saving the obtained time and assigning it to the remaining game time to achieve the update.

[0111] The maximum available time of the target indication information is calculated according to the following formula:

[0112] T 0 =T 0 -T R (J C )-T P (R(i))-T R (R(i))-T P (J(j))

[0113] Among them, T 0 is the remaining game time, T R (J C ) is the time required for radar to identify interference, T P (R(i)) is the time required for radar anti-interference measures, T R (R(i)) is the time required for the jammer to identify the radar measures, T P (J(j)) is the time required for the interference behavior to take effect.

[0114] If the remaining game time is greater than 0, the anti-interference method based on the Stackelberg game will continue to be used to continuously update the remaining game time; if the remaining game time is greater than 0, the radar will be determined to win according to the following conditions:

[0115] Case 1: T 0 +T P (R(i))>0, the radar is judged to be at a disadvantage;

[0116] Case 2: T 0 +T P (R(i))<0 and T 0 +T P (R(i))+T R (J C )>0, the radar is judged to be at a disadvantage;

[0117] Case 3: T 0 +T P (R(i))+T R (J C )<0 and T 0 +T P (R(i))+T R (J C )+T P (J(j))>0, the radar is judged to be in an advantageous position;

[0118] Case 4: T 0 +T P (R(i))+T R (J C )+T P (J(j))<0 and

[0119] T 0 +T P (R(i))+T R (J C )+T P (J(j))+T R (R(i))>0, it is determined that the radar is in an advantageous position.

[0120] If the radar is in an advantageous position, it is considered that the radar anti-interference is successful and the result is output; otherwise, it is considered that the radar anti-interference fails and the result is output. This method can enable the radar to take the lead in the confrontation with the jammer, implement interference countermeasures based on interference prediction, and improve the radar's winning probability in the anti-interference process. The higher the radar's recognition readiness rate for the interference pattern, the higher the radar's winning probability of this method. Figure 4 The simulation results of the method proposed in the present invention are compared with those of the existing anti-interference method. It can be seen that the winning probability of the anti-interference method proposed in the present invention is much higher than that of the control group.

[0121] In the embodiment of the present invention, the time required for the current round of interference behavior to take effect, the time required for the radar to identify the interference, the time required for the radar anti-interference measures, and the time required for the jammer to identify the radar measures are parameters set by prior information and do not change after the interference type and the anti-interference measure type are determined.

[0122] The above is only an optional implementation method for some implementation scenarios of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical concept of the solution of the present application, other similar implementation methods based on the technical ideas of the present application are also within the protection scope of the embodiments of the present application.
