Embodiment Construction

[0028] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0029] The technical solution of the present invention:

[0030] Step 1: Receive a dot trace sent by radar signal processing;

[0031] Step 2: The point trace information is three-dimensional polar coordinate information (R, A, E), and the radar scanning area is divided into several azimuth sectors (such as 64) in a clockwise direction, and the point trace is determined according to the azimuth information A of the point trace the sector in which it is located. At the same time, the three-dimensional polar coordinate information of the point trace is converted into rectangular coordinate information (X, Y, Z);

[0032] Step 3: Starting from the first circle of radar scanning, record all the trace information of the current scan circle, that is, the sector information where the trace is located, and the trace position information (X 0 ,Y 0 ,Z 0 ), circle numb...

Abstract

The invention relates to a real-time adaptive track initiation statistics method based on a plot density. Through counting the space plot density, one plot is for each initiation, a related spatial domain is demarcated adaptively, and the number of plots related to the plot in the spatial domain is counted. In the case of the track initiation, the average plot density of all plots used by the track is calculated, and according to the real-time statistics result and a preset threshold, the track initiation moment is determined, and false tracks can be effectively suppressed.

Description

technical field [0001] The invention belongs to the field of radar data processing, and in particular relates to an adaptive track initiation method based on point track density real-time statistics. Background technique [0002] Currently in the field of radar data, the traditional track initiation algorithm can obtain an effective initial target track when the probability of false alarm is relatively low (under weak clutter background). However, in the background of strong clutter, the problem with the traditional track initiation algorithm is that it is based on the process of expanding each track start with each measurement in the confirmation area, thus splitting into multiple candidate targets When the clutter density is high and the number of targets is large, a large number of false target tracks will be generated. [0003] Based on the above problems, an adaptive track initiation technology based on real-time statistics of track density is proposed. [0004] After...
