Radar global target track automatic initiation method based on environmental perception

Abstract

The invention provides a radar global target track automatic initiation method based on environmental perception. The method comprises the following steps of 1, carrying out azimuth distance grid quantization on a radar detection area, 2, comprehensively perceiving and evaluating clutter environment and intensity from a signal layer and a data layer by utilizing a point track and original echo data of the radar, and establishing an environment perception map,3, enabling each grid unit toobtain different area attributes through the environment perception map, mapping the point track informationto the corresponding network cell according to the mapping position, and giving the point track information to the attributes of the network cells, and 4, adopting a multi-channel parallel tracking processing architecture to carry out dual-channel automatic track initiation and conventional sea target channel on the target, adopting environment perception and target multivariate characteristics to carry out fine track initiation processing, adopting a low-speed small target channel, and adopting a DP-TBD-based weak and small target detection algorithm to carry out track initiation, and 5, carrying out system track integration, and outputting an initial integrated track.

Description

technical field [0001] The invention belongs to the field of radar data processing, and in particular relates to a method for automatically starting a track of a radar global target based on environment perception. Background technique [0002] For complex situations such as multiple sea conditions, multiple targets, and multiple motion modes in the detection area of ​​the maritime warning radar, there are certain technical difficulties in realizing the automatic initiation of global targets. Especially in the background of complex sea clutter, the automatic target detection performance and stable tracking ability are reduced, and sometimes it is only possible to rely on manual supplementary points for target acquisition, which seriously affects the quality of target track information. In order to reduce the operator's workload and improve the quality of radar intelligence, an automatic initiation technology for radar global targets based on environment perception is propose...

AI Technical Summary

Problems solved by technology

In the stage of automatic target discovery or tracking maintenance, according to the attribute characteristics of different areas where the target is located, comprehensively use the multiple feature information of the target for automatic start and automatic tracking, and overcome the traditional methods of automatic acquisition and processing of sea radar that only use the target position and motion state Data association with information such as the continuity of the "existence" of the detection target, automatic start is likely to cause problems such as wrong association and false track, which improves the accuracy of target track start and tracking stability under complex sea conditions, and improves the Shore-to-sea radar global automatic acquisition capability
