(1) Counter technology efficiency evaluation management module
The countering technology effectiveness evaluation management module is respectively connected with the countering equipment control module, the air-ground combined electromagnetic signal monitoring module, the unmanned aerial vehicle group motion control module and the unmanned aerial vehicle group motion state monitoring module through communication interfaces. Is used for realizing the following functions:
the control module is used for controlling the on-off of the detection equipment or implementing the detection action through the counter equipment control module, controlling the on-off of the striking equipment or implementing the striking action, collecting and storing state feedback data in the detection or striking process;

the system is used for reproducing the signal state change through a signal playback function of monitoring the load in the air-ground combined electromagnetic signal monitoring module, and reproducing the motion state of the unmanned aerial vehicle group in the test process through the unmanned aerial vehicle group motion control module.
(2) Control module of counter-control equipment
The countering technology of the unmanned aerial vehicle group is finally realized on the countering equipment of the unmanned aerial vehicle group, wherein the countering equipment comprises a detection equipment and a striking equipment. The counter-control device control module opens a communication link between the counter-control technology effectiveness evaluation management module and the counter-control device. The countering equipment control module is used for controlling the detecting equipment to be started or stopped or to execute the detecting action according to the control instruction of the countering technology effectiveness evaluation management module, controlling the striking equipment to be started or stopped or to execute the striking action, and receiving the detecting result and the equipment state information reported by the detecting or striking equipment. In order to ensure the expandability of the module and consider the cost and distance factors, the counter-control equipment control module adopts an IP-based network protocol to realize equipment control and data receiving and transmitting.
(3) Air-ground combined electromagnetic signal monitoring module
The air-ground combined electromagnetic signal monitoring module comprises a plurality of monitoring loads which are respectively distributed on each unmanned aerial vehicle of the unmanned aerial vehicle group, which is a countered object, and on the ground and used for carrying out overall process monitoring, analysis and playback on signals transmitted and received by the countering equipment of the unmanned aerial vehicle and signals actually received by each unmanned aerial vehicle in the unmanned aerial vehicle group and in a frequency range which needs to be concerned, so that the monitoring result can quantitatively reflect the change condition of the received signals of the unmanned aerial vehicle group in the motion process. The aerial electromagnetic signal monitoring is realized by using an unmanned aerial vehicle to carry monitoring load and is used for monitoring the states of active detection signals or striking signals such as interference, decoy and the like received by the unmanned aerial vehicle. The ground electromagnetic signal monitoring load is arranged near the countering device and is used for monitoring the state of a receiving signal of the detecting device or a transmitting signal of the striking device. In order to ensure the accuracy of the data recorded by the monitoring load, the antenna carrying the monitoring load should be closely installed near the receiving antenna of the unmanned aerial vehicle to be countered, and the antenna for monitoring the load on the ground should be installed near the receiving and transmitting antennas of the detecting equipment or the striking equipment.
The monitoring load can be realized by adopting a self-grinding customized signal acquisition module, and a lightweight real-time spectrum analyzer can also be adopted. The air-ground combined electromagnetic signal monitoring module can upload monitoring data to the counter technology performance evaluation management module through an interface for subsequent performance evaluation and further data analysis.
It should be noted that: the monitoring load has a signal generating function at the same time so as to reconstruct and reproduce the signal environment in the whole efficiency evaluation test process, thereby providing necessary conditions for iterative optimization of the reaction technology; the frequency range of the signal which can be received and recorded by the monitoring load needs to cover the satellite navigation frequency band of 1.2 GHz-1.6 GHz and the signal frequency band of the communication map such as 900MHz, 2.4GHz, 5.8 GHz; as the monitoring loads are distributed and deployed in the air and on the ground, satellite navigation time service equipment can be additionally arranged so as to carry out time synchronization on the recorded data among the loads. The application scenario of the air-ground combined electromagnetic signal monitoring module in the performance evaluation of the unmanned aerial vehicle group detection technology is shown in fig. 2, and the application scenario in the performance evaluation of the striking technology is shown in fig. 3. For efficiency evaluation of detection technology, active detection equipment such as echo radars and the like need ground electromagnetic signal monitoring load to monitor echo signals, and meanwhile electromagnetic signal monitoring load carried on an unmanned plane is needed to monitor the state of equipment transmitting signals. The efficiency evaluation of passive detection technologies such as signal detection or external radiation source radar and the like only needs the ground electromagnetic signal monitoring load to monitor the emitted or reflected signals of the unmanned aerial vehicle. The performance evaluation of the electromagnetic signal striking technology requires that monitoring loads are simultaneously distributed on the ground and the unmanned aerial vehicle so as to monitor the signal transmitted by the striking equipment and the signal state actually received by the unmanned aerial vehicle.
In summary, the air-ground combined electromagnetic signal monitoring module can record the whole process of signals transmitted and actually received by the ground reaction equipment and each unmanned aerial vehicle, truly reflect the change of the received signals of the unmanned aerial vehicle group in the motion process and the state of the signals transmitted or received by the reaction equipment, and enable the analysis of the action mechanism and the effect of the signals to be more accurate by comparing the signals with the data fed back by the unmanned aerial vehicle group motion state monitoring module.
(4) Unmanned aerial vehicle crowd motion control module
The invention relates to a technical efficiency evaluation system, wherein the movement state of an unmanned aerial vehicle group is controllable as a basis for completing corresponding evaluation, and different countering technical systems or evaluation scenes need to correspond to different machine group types and movement states. The unmanned aerial vehicle group motion control module is used for realizing the control instruction of the unmanned aerial vehicle group take-off and landing and the formation, position and speed control in the motion process according to the control instruction of the countering technical efficiency evaluation management module, thereby providing target object conditions for the unmanned aerial vehicle group countering technical efficiency evaluation and better evaluating the advantages and disadvantages of the countering technology.
(5) Unmanned aerial vehicle crowd motion state monitoring module
The unmanned aerial vehicle group target inevitably has the phenomena of communication link disturbance, navigation link cheating, pose control loop out of control and the like in the reverse control test process, so that the target cannot acquire and transmit real motion state information. Therefore, an independent unmanned aerial vehicle group motion state monitoring module must be constructed, and the position and speed data of each unmanned aerial vehicle must be monitored and stored, so that a basis is provided for the efficiency evaluation of the countering technology. The unmanned aerial vehicle group motion state monitoring module is composed and working principle is shown in an opinion figure 4.
The unmanned aerial vehicle crowd motion state monitoring module comprises hardware and software. The module hardware comprises a carrying unit and a radio station server. The carrying unit consists of a navigation receiver (a time service type receiver carried by an unmanned aerial vehicle in an air-ground combined electromagnetic signal monitoring module can be used) and a radio station. The navigation receiver is responsible for sampling the motion state of the carrier unmanned aerial vehicle according to a given time interval, sending the acquired information to a radio station, and then sending the acquired information to a radio station server by the radio station. It should be noted that the navigation receiver should operate in a non-countered navigation signal band, for example, when the evaluated countering technique is navigation spoofing, the spoofing signals are GPS, GLONASS and BDS B1 frequency points, and the receiver may be configured to operate in the BDS B3 frequency point. The radio station server is used for collecting target motion state data (namely positions, speeds and the like) of each unmanned aerial vehicle sent by each carrying unit, and sending the data to the countering technical efficiency evaluation management module after summarizing the data.
The unmanned aerial vehicle group countering technology efficiency evaluation method is realized based on the unmanned aerial vehicle group countering technology efficiency evaluation system.

Otherwise, continuing to wait for the detection result until the unmanned aerial vehicle group flies to the detection equipment, and switching to the step (6) after the evaluation fails;
(5) If the position information in the unmanned aerial vehicle group detection result reported by the detection equipment is matched with the unmanned aerial vehicle group position information reported by the unmanned aerial vehicle group motion state monitoring module, the detection is successful, the detection distance is the difference between the current position of the unmanned aerial vehicle group and the position of the detection equipment, and the step (6) is carried out; otherwise, the detection is unsuccessful, and the step (4) is carried out;
