Problems solved by technology
[0003] However, for a given networked radar system, there are always some uncertain factors that disturb the above inference results, such as multiple operating modes of radar nodes, radars of the same model, and communication between radar nodes are not necessarily all through wireless links Completion and other inferences that affect important radar nodes

The invention discloses a method for evaluating the priority of radar nodes in a networked radar system. It includes: using the AHP to analyze the radar signals of each radar node in the networked radar system to obtain the priority weight vector of each radar node, and using the traffic analysis method to analyze the radar signals between the radar nodes in the networked radar system. The communication signals of the communication links are analyzed to obtain the priority weight vectors of the radar nodes corresponding to each communication link, and the two priority weight vectors are calculated according to the predetermined basic probability assignment formula to obtain two priority weights. The basic probability assignment matrix of the value vector, and then fuse the two basic probability assignment matrices to obtain the priority weight vector of each radar node after fusion. The invention can eliminate the disturbance of uncertain factors to the radar node priority evaluation result, and improve the accuracy of the evaluation result.
Description
technical field [0001] The invention relates to the technical field of radar networks, in particular to a method for evaluating the priority of radar nodes in a networked radar system. Background technique [0002] The priority inference of radar nodes in a networked radar system is an important means of analyzing and recognizing the topology of a networked radar system. The inference of important radar nodes in a networked radar system, on the one hand, comes from the inference and analysis of important radar nodes, such as the assessment of the threat degree of radiation sources in radar networking systems (Lan Junjie, Chen Bei, Wang Min, Aerospace Electronic Countermeasures, Vol. 26 No. 3, pp. 61-64) mentions the evaluation of important radar nodes using the Analytic Hierarchy Process. On the other hand, it comes from the inference and analysis of the difference in communication flow between important radar nodes and responding radar nodes, such as the optimization algor...
