Embodiment

[0025] Embodiment comprises the following steps:

[0026] Step 1: first obtain the RCS data of various typical targets targeted by the cooperative detection system through electromagnetic simulation;

[0027] Step 2 is to fuse the RCS data according to the worst-case criterion, and use the minimum value among various typical target RCS values ​​in any observation direction as the RCS value in the observation direction after fusion;

Abstract

The present invention provides a method for generating an optimal topology structure of a cooperative detection system based on fusion of target characteristics, which utilizes typical target electromagnetic simulation RCS data and performs fusion of typical RCS data based on the worst-case criterion, that is, taking each observation direction The minimum value of the RCS value of each typical target is used as the RCS value in the observation direction, taking into account the pertinence and universality; then traverse all system deployment combinations according to the RCS value and propagation distance to calculate the corresponding system optimization target index; according to the calculation Results The optimal topology structure of the system was obtained through optimization, which solved the problem that the traditional radar equation was not suitable for analyzing the power range of the cooperative detection system.

Description

technical field [0001] The invention relates to radar detection technology and belongs to the field of radar signal processing, in particular to a collaborative detection radar system topology optimization algorithm based on worst case design criteria and MIMO radar detection technology. Background technique [0002] Using multi-radar network for cooperative detection, the target can be observed from multiple angles at the same time, and it has good detection performance. However, in a cooperative detection system composed of multiple radars, the power coverage of the system cannot be derived from the traditional radar equation. Whether each detection unit is within the power range depends on the specific detector used by the system and through numerical simulation or The actual test is obtained, the process is cumbersome and complicated, which is not conducive to optimization and real-time adjustment. However, the cooperative detection system uses far more resources than t...
