Description

Technical Field

[0001] This invention relates to the field of electromagnetic spectrum applications, and more specifically, to a multi-machine adaptive spectrum countermeasure allocation method based on a protocol table. Background Technology

[0002] In the context of networked swarm warfare, the key to conducting electromagnetic spectrum warfare lies in how to fully utilize limited spectrum resources to counter enemy radiation source signals. Current electromagnetic countermeasure resource allocation primarily relies on pre-battle planning and dynamic target allocation during combat to improve the utilization rate of networked resources. While these two methods can improve the utilization rate of electromagnetic countermeasure resources to some extent, the unpredictable and highly dynamic nature of the electromagnetic environment means that pre-battle planning has poor environmental adaptability, while real-time target allocation during combat requires interception, detection, sorting, identification, and resource reallocation of radiation source signals. Furthermore, the countermeasure target remains fixed during the time interval between allocations, resulting in low utilization rates and limited environmental adaptability of multiple spectrum countermeasure resources. Therefore, both methods offer limited improvement to the effectiveness of networked swarm warfare. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a multi-machine adaptive spectrum countermeasure allocation method based on protocol tables, which improves the overall utilization efficiency of spectrum countermeasure resources, meets the requirements of real-time performance and environmental adaptability, and supports the optimized application of cluster electromagnetic spectrum.

[0004] The objective of this invention is achieved through the following solution:

[0005] A multi-machine adaptive spectrum adversarial allocation method based on protocol tables includes the following steps:

[0006] The central node's spectrum countermeasures device formulates a countermeasures protocol table and distributes it to multiple spectrum countermeasures devices;

[0007] Multiple spectrum countermeasure devices detect signals and coordinate them according to the aforementioned countermeasure protocol table.

[0008] Furthermore, before the central node's spectrum countermeasures equipment formulates the countermeasures protocol table, the following steps are included:

[0009] Step 1: Set the number of each spectrum countermeasure device. Let the number of the i-th jammer be ID. x One of the spectrum countermeasure devices was identified as the central node, denoted by its ID number. X The central node spectrum countermeasures equipment is responsible for the resource allocation of all spectrum countermeasures equipment;

[0010] Step 2, set parameters, including: timed reconnaissance reporting period △Trep, timed adversarial allocation and protocol distribution period △Tj_Alloc, minimum adversarial bandwidth △RF_B, minimum adversarial frequency RF_BEG, maximum adversarial frequency RF_END, maximum number of adversarial frequency bands per adversarial device Num_Jam, and load the adversarial range JAREA to all adversarial devices;

[0011] Step 3: Every ΔTrep time, each spectrum countermeasure device periodically generates a signal list S_THREAT containing the parameters detected that match the countermeasure range JAREA, and sends it to the central node ID. X ;

[0012] Step 4: The central node records the list of reconnaissance target signals reported by each adversarial device and the number of adversarial devices reported in the previous △Trep time period (JNUM).

[0013] Furthermore, the formulation of the adversarial protocol table includes the following steps:

[0014] Step S1: Divide the frequency range [RF_BEG, RF_END] into several sub-bands {[RF_BEG, RF_BEG + i * ΔRF_B] using the minimum adversarial bandwidth ΔRF_B as the interval. i＝1,…,N_RF}, where N_RF takes the value of “(RF_END-RF_BEG) / △RF_B” rounded down;

[0015] Step S2: For each frequency band interval [RF_BEG, RF_BEG+i*△RF_B] i＝0,1,…,N_RF Count the sum of the number of signals reported by all adversarial devices (Time_SIG) i＝1,…,N_RF And the sequence of countermeasures device numbers {JNO} in descending order of the number of reported signals. ik} k＝1,2,... ;

[0016] Step S3: Record the countermeasure device ID x The set of adversarial target frequency bands is JRF_SET(ID) x And clear the countermeasure frequency bands of all countermeasure devices;

[0017] Step S4: Assign a set of adversarial target frequency bands JRF_SET(ID) to each adversarial device. x ), and set the protocol table.

[0018] Furthermore, step S4 includes the following sub-steps:

[0019] Step ①: Extract {[RF_BEG,RF_BEG+i*△RF_B]} i＝1,…,N_RFThe set of frequency bands in which Time_SIG is greater than zero is {[RF_BEG,RF_BEG+i*△RF_B]}. i∈SETJ};

[0020] Step 2: If the number of elements in SETJ is greater than JNUM*Num_Jam, then select {[RF_BEG,RF_BEG+i*ΔRF_B]}. i∈SETJ The top JNUM*Num_Jam frequency bands with the largest Time_SIG values ​​in} are used to form the countermeasure frequency band set {[RF_BEG,RF_BEG+i*△RF_B] i∈SETJ’ Otherwise, directly set {[RF_BEG,RF_BEG+i*△RF_B]} i∈SETJ} as the set of adversarial frequency bands {[RF_BEG,RF_BEG+i*ΔRF_B] i∈SETJ’};

[0021] Step 3: Set {[RF_BEG,RF_BEG+i*ΔRF_B] to... i∈SETJ’}Assign the value to the target frequency band set JRF_R to be allocated;

[0022] Step 4: For each adversarial target frequency band of each spectrum adversarial device, [RF_BEG,RF_BEG+i*ΔRF_B]([RF_BEG,RF_BEG+i*ΔRF_B]∈JRF_SET(ID) x The adversarial sub-node numbers are added to the adversarial sub-node number set in turn, with a maximum of one adversarial sub-node number added to each adversarial target frequency band each time, until no more can be added. This results in the following protocol table row J_SHEET_LINE:

[0023] Countermeasures target frequency band Adversarial master node number Adversarial secondary node number set [RF_BEG,RF_BEG+i*ΔRF_B] <![CDATA[ID x ]]> <![CDATA[{ID y_k } k＝1，；；； ]]>

[0024] Among them, ID y_k It is the sequence of countermeasure device numbers {JNO} jk} k＝1,2,… The set of adversarial frequency bands JRF_SET(ID) is satisfied. y_k ) k＝1,…,JN "Number of elements" and "Set of adversarial sub-node numbers for all adversarial target frequency bands {ID}" y_k} k＝1，；；； The corresponding ID y_k The sum of the occurrences of "Num_Jam" is not greater than the maximum number of countermeasure frequency bands Num_Jam, and belongs to the corresponding countermeasure device number sequence {JNO} in [RF_BEG, RF_BEG+i*ΔRF_B]. jk} k＝1,2,… The number;

[0025] Step 5: Combine the protocol table rows J_SHEET_LINE into a protocol table J_SHEET, and simultaneously set the adversarial time T against the master node. m The time T for the confrontation with the secondary node s and T m 、T s J_SHEET is distributed to all nodes.

[0026] Furthermore, step ③ includes the following sub-steps:

[0027] Step 31: Select the interference frequency band to be allocated from JRF_R with the largest sum of reported signal counts, denoted as [RF_BEG, RF_BEG+j*ΔRF_B], and the corresponding countermeasure device number sequence {JNO jk} k＝1,2,… ;

[0028] Step 32: For [RF_BEG, RF_BEG+j*ΔRF_B], add it to the countermeasure device number sequence {JNO}. jk} k＝1,2,… The foremost countermeasure device JNO jl The set of adversarial frequency bands JRF_SET(JNO) jl In ), and will not make the adversarial frequency band set of this node JRF_SET(JNO) jl The number of elements is greater than the maximum number of adversarial bands, Num_Jam;

[0029] Step 33: If [RF_BEG, RF_BEG+j*ΔRF_B] is successfully allocated, then remove [RF_BEG, RF_BEG+j*ΔRF_B] from JRF_R; if [RF_BEG, RF_BEG+j*ΔRF_B] is successfully allocated and JRF_R is not an empty set, then proceed to step i; if [RF_BEG, RF_BEG+j*ΔRF_B] is successfully allocated and JRF_R is an empty set, then exit the target allocation process.

[0030] Furthermore, the allocation process according to the adversarial protocol table includes the following steps:

[0031] At the start time, each spectrum countermeasure device sets a spectrum countermeasure status table as shown in Table 1; where JSTATE represents the countermeasure status of each spectrum countermeasure device, with 0 indicating idle and 1 indicating busy, JT_BEG indicating the start time of the countermeasure, and J_STAY indicating the duration of the countermeasure;

[0032] Table 1

[0033]

[0034]

[0035] If the local machine is in an adversarial idle state (i.e., local JSTATE = 0), when a signal sig satisfying the adversarial JAREA is observed at time t, the protocol table J_SHEET is queried to obtain the adversarial master node ID of [RF_BEG,RF_BEG+i*ΔRF_B] (RF(sig)∈[RF_BEG,RF_BEG+i*ΔRF_B]). MJ and the set of secondary node numbers {ID y_k} k＝1，… ;

[0036] If the machine ID l ≠ID MJ and Ignore it; otherwise, proceed to the next step.

[0037] Machine ID l =ID MJ If JSTATE = 0, then the local machine will engage in adversarial combat, and the adversarial time will be T. m ;

[0038] If the machine ID l ≠ID MJ And ID l ∈{ID y_k} k＝1，… Query the spectrum adversarial state table to obtain the ID. MJ The corresponding JSTATE, JT_BEG, and J_STAY;

[0039] If JSTATE = 0, then update the ID in the spectrum adversarial state table. MJ The corresponding rows are shown in Table 2 below;

[0040] Table 2

[0041]

[0042] If JSTATE = 1, then the local machine implements spectrum countermeasures for a duration of T. s Simultaneously update the {ID} in the spectrum adversarial state table. y_k} k＝1，… The rows corresponding to all nodes where JSTATE is 0 are shown in Table 3 below:

[0043] Table 3

[0044]

[0045] Furthermore, in updating the spectrum adversarial state table {ID y_k} k＝1，…The following steps are included: Real-time update of the spectrum adversarial status table: When the time is greater than or equal to JT_BEG+J_STAY of a certain row, set the corresponding JSTATE to 0.

[0046] Furthermore, the multiple spectrum countermeasure devices detect signals and perform allocation processing according to the countermeasure protocol table, including the following steps: the multiple spectrum countermeasure devices detect signals in real time and perform real-time allocation processing according to the countermeasure protocol table J_SHEET to achieve an adaptive spectrum countermeasure allocation effect.

[0047] Furthermore, at every interval ΔTj_Alloc, the central node formulates an adversarial protocol table J_SHEET and distributes it to all adversarial devices.

[0048] Furthermore, the adversarial range JAREA is defined as follows:

[0049] {RF j , △RF j PW j , △PW j PRI j , △PRI j MIN_S_T j} j＝1,2,…,M

[0050] Among them, RF j , △RF j PW j , △PW j PRI j , △PRI j MIN_S_T j These represent the frequency, frequency tolerance, pulse width, pulse tolerance, repetition period, repetition period tolerance, and minimum duration of the j-th signal, respectively.

[0051] In step 3, the detected parameters that conform to the adversarial range JAREA include: signal frequency RF_T, pulse width PW_T, pulse repetition period PRI_T, signal duration S_T, and signal occurrence count S_Num.

[0052] The beneficial effects of this invention include:

[0053] The technical solution of this invention improves the overall utilization efficiency of spectrum countermeasure resources while meeting the requirements of real-time performance and environmental adaptability when facing complex electromagnetic dynamic games, and supports the optimized application of cluster electromagnetic spectrum.

[0054] The technical solution of this invention overcomes the long process of "environmental change, resource allocation, and confrontation execution" faced by traditional methods that rely on pre-war planning and dynamic target allocation during wartime, and improves the environmental adaptability of multiple spectrum confrontation resources.

[0055] Compared with the currently widely used spectrum countermeasure resource scheduling methods, the technical solution of this invention can enable multiple spectrum countermeasure resources to cooperate dynamically in real time according to environmental changes after the countermeasure target is allocated, rather than waiting for the allocated target. This achieves the effect of "automatic cooperation of multiple electromagnetic spectrum countermeasure resources" and improves the overall countermeasure effectiveness of networked cluster operations.

[0056] The technical solution of this invention improves the utilization rate of multiple spectrum countermeasure resources in real time, and is particularly suitable for networked intelligent cluster countermeasures. Attached Figure Description

[0063] The purpose of this invention is to find a multi-machine adaptive spectrum adversarial allocation method based on protocol tables, especially in the context of networked cluster applications, when facing complex electromagnetic dynamic games, to improve the overall utilization efficiency of spectrum adversarial resources while meeting the requirements of real-time performance and environmental adaptability, and to support the optimized application of cluster electromagnetic spectrum.

[0064] In a specific implementation, the specific steps of the technical solution of the present invention are as follows:

JAREA is defined as follows, where RF... j ΔRF j PW j ΔPW j PRI j ΔPRI j MIN_S_T j These represent the frequency, frequency tolerance, pulse width, pulse tolerance, repetition period, repetition period tolerance, and minimum duration of the j-th signal, respectively.

[0067] {RF j ΔRF j PW j ΔPW j PRI j ΔPRI j MIN_S_T j} j＝1,2,…,M

[0068] (3) Every △Trep time interval, each countermeasure device periodically generates a signal list S_THREAT containing the detected signals that conform to the countermeasure range JAREA, including "signal frequency RF_T, pulse width PW_T, pulse repetition period PRI_T, signal duration S_T, and signal occurrence count S_Num", and sends it to the central node (ID). X );

[0069] (4) The central node records the list of reconnaissance target signals reported by each adversarial device and the number of adversarial devices (JNUM) reported in the previous ΔTrep time interval. Every ΔTj_Alloc time interval, the central node formulates an adversarial protocol table (J_SHEET) and distributes it to all adversarial devices. The specific steps for formulating the protocol table are as follows:

[0070] a) Divide the frequency range [RF_BEG, RF_END] into several sub-bands {[RF_BEG, RF_BEG + i * ΔRF_B] with an interval of ΔRF_B. i＝1,…,N_RF}, where N_RF takes the value of “(RF_END-RF_BEG) / ΔRF_B” rounded down;

[0071] b) For each frequency band interval [RF_BEG, RF_BEG + i * ΔRF_B] i＝0,1,…,N_RF Calculate the sum of the number of signals reported by all adversarial devices (S_Num) for Time_SIG. i＝1,…,N_RF And the sequence of countermeasures device numbers {JNO} in descending order of the number of reported signals. ik} k＝1,2,... ;

[0072] c) Record the ID of the anti-counterfeiting device x The set of adversarial target frequency bands is JRF_SET(ID) x And clear the countermeasure frequency bands of all countermeasure devices;

[0073] d) Assign a set of adversarial target frequency bands to each adversarial device using JRF_SET(ID). x The protocol table is set up, and the specific processing steps are as follows:

[0074] ①Extract {[RF_BEG,RF_BEG+i*△RF_B] i＝1,…,N_RF The set of frequency bands in which Time_SIG is greater than zero: {[RF_BEG,RF_BEG+i*ΔRF_B] i∈SETJ};

[0075] ② If the number of elements in SETJ is greater than JNUM*Num_Jam, then select {[RF_BEG,RF_BEG+i*ΔRF_B]}. i∈SETJ The top JNUM*Num_Jam frequency bands with the largest Time_SIG values ​​in} are used to form the set of adversarial frequency bands {[RF_BEG,RF_BEG+i*ΔRF_B] i∈SETJ’ Otherwise, directly set {[RF_BEG,RF_BEG+i*ΔRF_B]}; i∈SETJ} as the set of adversarial frequency bands {[RF_BEG,RF_BEG+i*ΔRF_B] i∈SETJ’};

[0076] ③Place {[RF_BEG,RF_BEG+i*ΔRF_B] i∈SETJ’ The values ​​are assigned to the target frequency band set JRF_R to be allocated, and the allocation is performed as follows:

[0077] i. Select the sum of the number of reported signals (S_Num) from JRF_R (Time_SIG) i The largest unallocated interference frequency band can be denoted as [RF_BEG, RF_BEG + j*△RF_B], and the corresponding countermeasures device number sequence {JNO}. jk} k＝1,2,… ;

[0078] ii. For [RF_BEG, RF_BEG+j*△RF_B], add it to the countermeasure device number sequence.

[0081] iii. If [RF_BEG, RF_BEG+j*△RF_B] is successfully allocated, then [RF_BEG,

[0082] Remove RF_BEG+j*△RF_B from JRF_R;

[0083] iv. If [RF_BEG, RF_BEG+j*△RF_B] is successfully allocated and JRF_R is not an empty set, then proceed to i; if [RF_BEG, RF_BEG+j*△RF_B] is successfully allocated and JRF_R is an empty set,

[0084] Then exit the target allocation process.

[0085] ④ For each spectrum countermeasure device (numbered ID) x For each adversarial target frequency band [RF_BEG,RF_BEG+i*ΔRF_B]([RF_BEG,RF_BEG+i*ΔRF_B]∈JRF_SET(ID) x Add adversarial sub-node numbers to the adversarial sub-node number set in turn, adding at most one adversarial sub-node number per adversarial target frequency band each time, until no more can be added. This will result in the following protocol table line J_SHEET_LINE:

[0086] Countermeasures target frequency band Adversarial master node number Adversarial secondary node number set [RF_BEG,RF_BEG+i*△RF_B] <![CDATA[ID x ]]> <![CDATA[{ID y_k } k＝1，。。。 ]]>

[0089] (5) Multiple spectrum countermeasure devices conduct reconnaissance signals and perform real-time allocation processing according to the countermeasure protocol table J_SHEET to achieve adaptive spectrum countermeasure allocation effect. The specific steps are as follows.

[0090] At the start time, each spectrum countermeasure device sets its spectrum countermeasure status table as shown below. Here, JSTATE represents the countermeasure status of each spectrum countermeasure device (0 for idle, 1 for busy), JT_BEG represents the countermeasure start time, and J_STAY represents the countermeasure duration.

[0164] Step 4: For each adversarial target frequency band of each spectrum adversarial device, [RF_BEG,RF_BEG+i*ΔRF_B]([RF_BEG,RF_BEG+i*ΔRF_B]∈JRF_SET(ID) x The adversarial sub-node numbers are added to the adversarial sub-node number set in turn, with a maximum of one adversarial sub-node number added to each adversarial target frequency band each time, until no more can be added.
