DETAILED DESCRIPTION
[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0015] like Figure 1 As shown, a comprehensive radio frequency system overall effectiveness evaluation method includes the following steps: 1) Establish an overall performance evaluation index system for integrated RF systems; The performance evaluation index system of the integrated radio frequency system consists of five layers, from top to bottom: overall performance layer, functional task performance layer, task capability layer, technical performance layer and technical performance evaluation index layer; the details are as follows: The overall effectiveness layer refers to the overall effectiveness of the integrated radio frequency system in performing various integrated tasks such as detection, electronic countermeasures, reconnaissance, and communications.
[0016] The functional mission effectiveness layer includes the single effectiveness of detection effectiveness, electronic countermeasure effectiveness, reconnaissance effectiveness and communication effectiveness; Mission capability layer, including: Technical capabilities of detection effectiveness: detection signal emission capability, signal processing capability; Technical capabilities of electronic countermeasure effectiveness: electronic countermeasure signal emission capability and signal guidance capability; Technical capabilities of reconnaissance effectiveness: signal detection capability, signal processing capability; Technical capabilities of communication performance: network capacity, latency parameters, transmission quality; Technical performance layer, including: Performance indicators of detection signal transmission capability: maximum operating distance D1, detection accuracy D2; Performance indicators of signal processing capability: signal processing data rate D3, resolution D4, multi-target capacity D5, and anti-interference capability D6; Performance indicators of electronic countermeasure signal transmission capability: maximum transmission power D7, instantaneous interference bandwidth D8, minimum interference distance D9; Performance indicators of signal guidance capability: interference guidance time D10, azimuth aiming accuracy D11, multi-target interference capability D12; Performance indicators of signal detection capability: detection sensitivity D13, interception probability D14; Performance indicators of signal processing capability: frequency measurement capability D15, direction finding capability D16, simultaneous multi-target tracking capacity D17, signal sorting capability D18; Performance indicators of network capacity: number of network nodes D19; Performance indicators of delay parameters: synchronization time D20, transmission delay D21; Performance indicators of transmission quality: transmission rate D22, bit error rate D23, frame loss rate D24; 2) Collect the performance index values of the technical performance layer, and perform modeling and normalization evaluation of performance parameters; The performance indicators of the technical performance layer are directly obtained through system equipment attribute parameters, obtained through system equipment attribute parameter representation, or obtained through modeling; Most performance indicators can be obtained through system attribute parameters, such as the performance indicators D1, D2, D3, D4, and D5 of the detection function, the performance indicators D7, D8, D9, D10, D11, and D12 of the electronic countermeasure function, the performance indicators D13, D14, D15, D16, and D17 of the reconnaissance function, and the performance indicators D19, D20, D21, D22, D23, and D24 of the communication function. Among them, the multi-target interference capability D12 can be characterized by the parameter of the number of simultaneous multi-target interference batches, the frequency measurement capability D15 can be characterized by the frequency measurement accuracy error parameter of the reconnaissance function, the direction finding capability D16 can be characterized by the direction finding error parameter of the reconnaissance function, and the simultaneous tracking of multiple targets capacity D17 can be characterized by the number of simultaneous tracking of multiple targets batches parameter of the reconnaissance function.
[0017] A small number of performance indicators can be obtained based on the system qualitative parameters combined with the expert system method or modeling. For example, the performance indicator of the detection function, the anti-interference capability D6, can be evaluated based on system characteristics such as frequency conversion bandwidth, the number of anti-interference methods, and anti-interference ability through a neural network model or an expert system scoring method (for example, if the anti-interference capability index of a system with 10 anti-interference methods is 1, then the capability index of a system with only 8 anti-interference methods is 0.8, or an expert evaluation can be performed based on the anti-interference capability parameters), and the signal sorting capability D18 of the reconnaissance function can be measured by the ability to identify and eliminate false targets and to perform multi-target fusion processing, and can be given through an expert system or a neural network model.
[0018] Then the obtained indicators are normalized.
[0019] Each evaluation index takes a value between [0,1]. When the evaluation index value is positively correlated with the comprehensive performance, the sample Normalized value for: ; When the evaluation index value is negatively correlated with the comprehensive performance, the sample Normalized value for: .
[0020] 3) Determine the weight of each performance indicator, build an efficiency evaluation model for the integrated RF system, and conduct an overall efficiency evaluation of the integrated RF system.
[0021] The weights of the evaluation indicators in the evaluation indicator system constructed by fitting analysis calculation are as follows: 0.0371; 0.0754; 0.1418; 0.1012; 0.0607; 0.0338; 0.0165; 0.0154; 0.0311; 0.0087; 0.0583; 0.02; 0.085; 0.073; 0.035; 0.035; 0.022; 0.0185; 0.011; 0.018; 0.018; 0.0225; 0.031; 0.031].
[0022] Comprehensive RF system overall effectiveness evaluation S, S=∑d i *w i ; Among them, d i is the performance index value corresponding to the performance index Di, w i is the weight coefficient corresponding to the performance index Di.
[0023] According to the task requirements and specific usage process, an adaptive performance evaluation model can be further constructed on the method of the present invention. In this embodiment, the selection process of the comprehensive performance evaluation index of the integrated RF integrated system is explained through the integrated RF system air defense and anti-missile process. The main action process of the integrated RF system can be divided into three steps: early warning, tracking and identification, and interception.
[0024] 1) In the early warning stage, the integrated radio frequency system conducts active and passive detection of the target's incoming direction, and strengthens observation and vigilance of anti-ship missiles flying across the sea. After detecting the target information, the precise location and motion elements of the target are discovered and obtained, the parameters of the incoming target are analyzed, and the judgment results are uploaded to the superior through the communication subsystem of the integrated radio frequency system. From the above combat process, it can be seen that the combat use of the integrated radio frequency system is related to the scene environment and conditions of the battlefield. Each functional subsystem needs to decide whether to participate in combat coordination based on the combat mission. In the detection stage, we can summarize the main application process of the integrated radio frequency system in the process of air defense and anti-missile operations of maritime platforms as "detection + communication" coordination. Therefore, the establishment of a comprehensive effectiveness evaluation index system such as Figure 2 As shown; For the detection and communication integrated radio frequency system, the 12 performance indicators can be calculated according to the importance of the indicators using the hierarchical analysis method and their weights are as follows: W=(0.0619; 0.1256; 0.2363; 0.1687; 0.1012; 0.0563; 0.0275; 0.0256; 0.0519; 0.0145; 0.0971; 0.0334); According to the weight of each performance indicator, a performance evaluation model of the integrated radio frequency system for detection and communication is constructed to conduct a comprehensive performance evaluation of the integrated radio frequency system for detection and communication.
[0025] 2) During the interception phase, the integrated radio frequency system needs to conduct electronic reconnaissance and electronic interference on enemy targets. The integrated radio frequency system for reconnaissance and interference is used to conduct an all-round search for the electromagnetic radiation signals of air and sea targets. After the active tracking signal of the enemy's incoming target's seeker is found, the integrated radio frequency system for reconnaissance and interference is used to continuously conduct reconnaissance and identify the electromagnetic characteristics of the enemy's incoming target, and implement electronic interference suppression or electronic deception on the incoming seeker target to implement coordinated defense against our sea or air platforms. From the above combat process, it can be seen that the main application process of the integrated radio frequency system can be summarized as "reconnaissance + electronic countermeasures" coordination. Therefore, the main process of establishing a comprehensive effectiveness evaluation index system is basically the same as the "detection + communication" mode. The comprehensive effectiveness index system under this application mode is as follows: Figure 3 As shown, it covers the main performance indicators of the "reconnaissance and electronic countermeasures" functions of the reconnaissance and jamming integrated radio frequency system during the interception phase of air defense and anti-missile operations.
[0026] For the integrated radio frequency system of reconnaissance and electronic countermeasures, the weights of the 12 performance indicators can be calculated according to the importance of the indicators using the hierarchical analysis method as follows: W=(0.2125; 0.1815; 0.0877; 0.0875; 0.0555; 0.0459; 0.0275; 0.0455; 0.0455; 0.0559; 0.0775; 0.0775); According to the weight of each performance indicator, an effectiveness evaluation model of the integrated radio frequency system for reconnaissance and electronic countermeasures is constructed to conduct a comprehensive effectiveness evaluation of the integrated radio frequency system for reconnaissance and electronic countermeasures.
[0027] 3) If the comprehensive effectiveness of the integrated RF system in the entire combat process is to be considered, the indicator systems of the above early warning stage and interception stage should be integrated to form a complete indicator system for the overall effectiveness evaluation of the integrated RF system.
[0028] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the appended claims of the present invention.
