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 operates around the clock, day and night, unobstructed by fog, clouds, or rain. Radar uses the scattering of electromagnetic waves by targets to detect them and obtain information such as their range, speed, and angle. It is a crucial sensor for detecting and identifying targets and guiding weapons to complete attack missions. When detecting non-cooperative targets, radar may be subject to various active and passive interference, necessitating the implementation of appropriate anti-interference measures to achieve victory in electromagnetic spectrum warfare. In electromagnetic spectrum warfare, radars must develop interference perception, interference pattern recognition, and corresponding anti-interference measures, as well as methods for the rational application of these anti-interference measures throughout the entire radar-jammer interaction process.

[0003] Because the confrontation between radar and jammers is a dynamic process, adaptive, intelligent jammers' jamming tactics and waveform patterns are not static during a single offensive and defensive confrontation. If a particular jammer is successfully suppressed by the radar system and fails to work, the jammer will switch to a different jamming pattern. Therefore, even if a radar implements anti-jamming measures and gains an advantage in a particular round, it does not guarantee mission success and ultimate victory.

[0004] Conventional radar countermeasures against jammers fail to predict jamming behavior and therefore fail to proactively counteract it. They only select a countermeasure upon detection of interference, resulting in a passive response. When faced with multiple countermeasures, they often choose the one with the greatest immediate benefit. This approach fails to fully consider the continuous and dynamic nature of the interaction between the radar and the jammer, nor does it take into account the ultimate conditions for the radar's success in implementing a corresponding countermeasure. Summary of the Invention

[0005] The purpose of the present invention is to address the scenario where conventional radar anti-interference methods fail to predict interference measures. There are two problems: 1) passively responding to interference without predicting interference behavior. Anti-interference measures are only taken after the radar is interfered with, which cannot seize 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 ultimate winning conditions. A radar anti-interference method based on Stackelberg game is proposed.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions.

[0007] The radar anti-interference method relies on a radar anti-interference system, which includes 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 win-lose determination module;

[0009] The interference identification module identifies 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 according to the interference type currently faced by the radar as a candidate radar behavior;

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

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

[0013] The jamming benefit pre-determination module determines the jamming type with the maximum benefit 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 jamming behavior to take effect, the time required for the radar to identify the jamming, the time required for the radar to take anti-jamming measures, the time required for the jammer to identify the radar measures, and updates the remaining game time as the game progresses;

[0016] The win / loss 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 are effective and the jammer's interference is not effective, the radar completes the anti-interference function;

[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 measure selection module, the interference type prediction module, the interference benefit pre-determination module, the anti-interference measure selection module, the interference type control module, the timing module, and the win-lose determination module will continue to be executed;

[0020] The method comprises the following steps:

[0021] S1, parameter setting;

[0022] The parameters are 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 to take 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 candidate radar behaviors;

[0025] S4, the jamming type prediction module determines the jamming type that the jammer may select if the radar adopts a certain 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 subsequent candidate radar 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 by the game process and updates the remaining game time;

[0030] The time consumed in the game process includes: the time it takes for the interference recognition module to identify the current interference type, the time it takes for the radar anti-interference measures to take effect, the time it takes for the jammer to identify the anti-interference measures, and the time it takes for the jammer's interference type to take effect;

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

[0032] S9, the winning / 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, the process jumps to S2;

[0033] The determination of whether the game is over is specifically as follows: determining whether the remaining game time is negative; if so, the game and the timing are both over; otherwise, it indicates that the game is not over and the process jumps to S2;

[0034] Anti-interference effect evaluation, to assess whether the anti-interference measures have played a role;

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

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

[0037] The method of improving the radar's recognition rate of 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 recognition 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 an embodiment of the present invention, the radar uses the Stackelberg game to predict the type of interference a jammer will implement and take anti-interference measures in advance to counteract the type of interference 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 jammer's anti-interference measures are continuously selected in a dynamic game. This Stackelberg game-based anti-interference method can fully utilize prior information in the confrontation between radar and jammers, seize the initiative, turn passivity into initiative, change radar behavior logic, and implement interference restraint based on interference prediction. This method is applicable to confrontation scenarios between radars and jammers in the air, at sea, and on land, and has a wide range of applications and good prospects for promotion.

[0041] Beneficial effects

[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 methods:

[0043] 1. The method changes the radar's anti-interference measure selection logic and implements interference countermeasures based on interference prediction. After identifying interference, the optimal anti-interference measure can be selected from a variety of alternative anti-interference measures, enabling it to restrain the next round of interference types and always gain the upper hand in the 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] To achieve radar anti-interference, the present disclosure provides a radar anti-interference method based on Stackelberg game. The following is a detailed description of each embodiment of the present disclosure in conjunction with the accompanying drawings.

[0054] Embodiment 1

[0055] As Figure 1 , Figure 2 , Figure 3 and Figure 4 indicated, the embodiment of the present application provides a radar anti-jamming method based on Stackelberg game, which contains radar anti-jamming measure selection, radar anti-jamming method timing and other links, from Figure 1 It can be seen that the radar anti-jamming method comprises the following steps:

[0056] Step 1, an interference identification module identifies the interference received by the radar at a certain identification rate and determines the interference type;

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

[0058] Step 2, an anti-jamming measure selection module selects, from all anti-jamming measures, an anti-jamming measure capable of suppressing the current interference type as a radar candidate behavior, according to the interference type currently faced by the radar;

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

[0060] Step 3, an interference type prediction module predicts the subsequent interference behavior according to Stackelberg game, and judges the interference type that the jammer is likely to select if the radar takes a certain candidate behavior;

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

[0062] Step 4, a jammer maximum benefit interference type determination module determines the maximum benefit interference type of the jammer for each subsequent radar candidate behavior;

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

[0064] Step 5, an anti-jamming measure selection module selects the optimal anti-jamming measure from all subsequent radar candidate behaviors;

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

[0066] Step 6, an interference type control module selects the next interference type after the jammer determines the radar anti-jamming measure.

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

[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 summary;

[0071] The time consumed in the game process includes: the time it takes for the interference recognition module to identify the current interference type, the time it takes for the radar anti-interference measures to take effect, the time it takes for the jammer to identify the anti-interference measures, and the time it takes for the jammer's interference type to take effect;

[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 / losing determination module determines whether the radar has completed anti-interference when the remaining game time is just reduced to zero;

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

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

[0076] The win / loss 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 are effective and the jammer's interference is not effective, the radar completes the anti-interference function;

[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 and jumps 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 results 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 radar anti-interference method relies on the timing module process, such as 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 time 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 identification 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 both ended; 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 prior information obtained from long-term research on the confrontation between radar and jammers.

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

[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 from the radar starting to take anti-interference measures to the time the measures are required to 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 jamming behavior refers to the length of time it takes for the jammer to start taking jamming measures and for the measures to successfully jam 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 behaviors that can be controlled by radar and interference.

[0097] In an embodiment of the present invention, the radar uses the Stackelberg game to predict the type of interference a jammer will implement and take anti-interference measures in advance to counteract the type of interference 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 jammer's anti-interference measures are continuously selected in a dynamic game. This Stackelberg game-based anti-interference method can fully utilize prior information in the confrontation between radar and jammers, seize the initiative, turn passivity into initiative, change radar behavior logic, and implement interference restraint based on interference prediction. This method is applicable to confrontation scenarios between radars and jammers in the air, at sea, and on land, and has a wide range of applications and good prospects for promotion.

[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 encountered 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 can be taken by the radar 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 possible interference types as the candidate measure of the jammer.

[0102] The jamming benefit pre-determination module selects, for each candidate radar behavior, a jamming type that can maximize the jammer benefit by restraining the candidate radar behavior from the candidate jammer measures.

[0103] The anti-interference measure selection module finds the anti-interference behavior that maximizes the radar benefit from all the pairs of radar candidate behavior and jammer type, 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-interference measures, find the J C All measures, the number is recorded as N(J C ) types, and the number of each anti-interference measure is

[0106] For each anti-jamming measure, find the type of jammer that can overcome it to maximize the benefit to the jammer.

[0107] Record the corresponding radar gain at this time

[0108] Find 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 target indication information is calculated according to the following formula:

[0112] T0=T0-T R (J C )-T P (R(i))-T R (R(i))-T P (J(j))

[0113] Among them, T0 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 is continued to be used, and the remaining game time is continuously updated. If the remaining game time is greater than 0, the radar is determined to have won according to the following conditions:

[0115] Case 1: T0+T P (R(i))>0, the radar is judged to be at a disadvantage;

[0116] Case 2: T0+T P (R(i))<0 and T0+T P (R(i))+T R (J C )>0, the radar is judged to be at a disadvantage;

[0117] Case 3: T0+T P (R(i))+T R (J C )<0 and T0+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: T0+T P (R(i))+T R (J C )+T P (J(j))<0 and

[0119] T0+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 initiative 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 description is only an optional implementation method for some implementation scenarios of this application. It should be pointed out that for ordinary technicians in this technical field, without departing from the technical concept of the solution of this application, the use of other similar implementation methods based on the technical ideas of this application also falls within the protection scope of the embodiments of this application.
