Embodiment Construction

[0043] Below in conjunction with accompanying drawing, the present invention will be further described, and concrete steps are as follows:

[0044] Such as figure 1 As shown, 1. Establish a parallel track tracking architecture, divide the tracking architecture into six independent tracking channels that do not interfere with each other, including fast air target channel, slow air target channel, helicopter and slow low-altitude target channel, sea surface routine Target channel, sea surface fast and weak target channel, sea surface slow weak and small target channel.

[0045] Such as figure 2 As shown, 2. The track is automatically initiated by means of target motion statistics and feature recognition in each tracking channel. The process is as follows:

[0046] (1) The generation and maintenance of candidate tracks are realized through the following steps:

[0047] A. Candidate track start

[0048] Let Z j (k) is the jth measurement point trace of the kth scan period, w...

Abstract

The invention discloses a warning radar multi-target multi-channel parallel tracking processing method. The method comprises the steps that firstly, a parallel flight path tracking framework is built,and the tracking framework is divided into a plurality of non-interfering independent tracking channels; secondly, the target motion statistics and feature recognition means in the tracking channelsare used for automatically starting the flight path; then, according to motion feature setting relevance, filtering models and parameters of the different tracking channels, the official flight path is tracked, and a target likelihood function is used for performing flight path tracking quality evaluation; finally, on the basis of the parallel fusion framework and a flight path management strategy, the multi-channel tracking results are unified, and the comprehensive and accurate warning area target posture is obtained. The sea surface and aerial targets observed by a warning radar are dividedinto the multiple channels for finding and maintaining the flight path, and therefore the effects of comprehensively and accurately finding the targets, and tracking different types of targets in a high-precision and high-stability mode are achieved.

Description

technical field [0001] The invention relates to a warning radar tracking processing method, in particular to a warning radar multi-target multi-channel parallel tracking processing method. Background technique [0002] The warning radar is responsible for early warning and monitoring of suspicious targets, and often has a relatively large observation area, which can comprehensively deal with a large number of sea and air targets in the area, suppress the interference of complex situations such as cloud and rain, sea clutter, and ground object echoes, and ensure Object tracking quality is a challenging task. When the traditional radar target tracking method is used to process the warning radar data, it is difficult to select the tracking model and configure the parameters, and the tracking of different types of targets is often out of proportion, resulting in many missed detections and false targets. Problems such as starting, trajectory tracking instability, and poor tracki...
