Problems solved by technology

However, the existing research mainly focuses on the spatial separation characteristics of multi-station radar when discussing the multi-station radar moving target detection method, but ignores the research on the multi-station radar moving target detection method based on the fusion criterion, which leads to the existing multi-station radar motion Object detector performance is poor

Embodiment Construction

[0067] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the invention.

[0068] Technical scheme of the present invention comprises the following steps:

[0069] The first step is to establish the multi-station radar moving target echo model.

[0070] consider as figure 1 The multi-static radar moving target detection scenario shown. A multi-station radar containing M transmitting base stations Tx m(m=1,2,...,M) and N receiving base stations Rx n(n=1,2,...,N) is used to detect |The target Tgt moving in a certain direction β, and the observation angles of the transmitting base station Tx m and receiving base station Rx n relative to the target (that is, t...

Abstract

The objective of the invention is to provide a multi-station radar moving target detection method based on fusion criteria. A multi-station radar moving target detector is obtained through derivation on the basis of designing the weight coefficient of each two-station radar unit so that weight accumulation of information of all the receiving base stations can be realized, and thus the objective of enhancing the performance of multi-station radar moving target detection can be achieved.

Description

technical field [0001] The invention belongs to the field of multi-station radar moving target detection and relates to a multi-station radar moving target detection method based on fusion criteria. Background technique [0002] As an emerging radar system, multi-station radar has significant advantages over single-station radar in target detection and positioning, parameter estimation, tracking and identification, etc., and has broad application prospects and value in the field of moving target detection. more and more scholars' attention. [0003] The target information obtained by single-station radar detection is relatively simple; while multi-station radar contains multiple space-separated transmitting and receiving base stations, which can detect targets from different angles and then obtain target information at multiple azimuth angles (such as target amplitude, speed, etc. ), and integrate the target information received by each base station for final joint processi...
