Embodiment Construction

[0030] Such as figure 1 , figure 2 As shown, the present invention requires that signal processing can provide more information for data processing, including: the signal-to-noise ratio of video, the original video, the MTD channel number of video, the MTD gating result of video, the clutter map gating result of video And information such as the height of the video, the more information the better.

[0031] according to Figure 8 The dot condensation as shown mainly includes the following processes.

[0032] 1. Carry out distance aggregation for the video, condense the videos distributed in the distance of the same target into a "distance block", save the azimuth, distance, height, maximum signal-to-noise ratio, distance span, MTD channel number, and MTD gating of the distance block The sum of , the sum of the clutter map gating, the number of videos that make up the distance block and the sum of the signal-to-noise ratios of all the videos that make up the distance block;...

Abstract

The invention belongs to the content of the radar data processing field, and relates to the detection and tracking algorithm of a radar. In the invention, two methods, i.e., a trace point quality decision and a track quality decision are adopted so as to finish full automatic data processing with practical significance. On one hand, the problem of false track caused by a great number of false alarms in a complex clutter background can be solved, and on the other hand, the initial speed of the track can also be improved at the same time. By using the full automatic data processing method provided by the invention, the usefulness of the radar in use can be brought into play, and the labor intensity of commanders and fighters can also be mitigated at the same time.

Description

technical field [0001] The invention belongs to the field of radar data processing and relates to radar detection and tracking algorithms. Background technique [0002] Modern warfare requires radar data processing to have the function of automatic recording, and this method is helpful for the realization of this function. [0003] The goal of data processing is to find the real target in the detection video provided by signal processing, and give the parameters of the target's operation in space, and at the same time filter out the false targets caused by meteorological clutter, ground clutter and active interference. Data processing mainly includes two parts: point trace processing and track processing. Track processing needs to correlate the detection results provided by signal processing, condense the correlation results into a track, and determine the parameters of the track, such as azimuth, distance, height, radial velocity, and discovery time. The object of track p...
