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;

[0028] Step 3 System and target parameter settings:

[0029] Step 3.1 Set system parameters: including the number of nodes N, the observation area, and the deployable area (that is, all possible node coordinate combinations);

[0030] Step 3.2 Set node performance parameters: the backscattering area of ​​a typical target is σ, which meets a certain detection probability P d and false alarm probability P fa In the case of the maximum operating distance R max ;

[0031] For example, suppose a section of horizontal coastline, the system nodes ar...

Abstract

The invention provides a target feature fusion based cooperation detection system optimal topology generation method; and the method is as follows: typical target electromagnetic simulation RCS data is used, typical RCS data fusion based on worst-case criterion is performed, a minimum value of RCS value of each typical target in each observation direction is used as the RCS value in the observation direction, and pertinence and universality are both taken into account; then according to the RCS value and propagation distance, all system optimization target indexes corresponding to system deployment combination calculation are traversed; and an optimal topology is obtained by optimization of the calculated results. The method solves the problem that a traditional radar equation is not suitable for the analysis of the formidable force range of a 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...
