An Evaluation Method for the Initial Comprehensive Quality of Searching Radar Tracks

Abstract

The invention discloses a method for evaluating the initial comprehensive quality of a search radar track, and belongs to the technical field of radar data processing track initial. Aiming at the problem of suppressing false tracks and improving the correct rate of track initiation in the process of radar data processing track initiation, this method comprehensively uses the quality of elevation angle fluctuation, the quality of elevation angle, the quality of off-axis angle, the quality of the same distance, and the quality of Doppler Channel number quality and Doppler coincidence quality, amplitude quality, correlation point quantity quality, clutter map quality, environment perception quality, correlation probability quality calculation, distance residual quality, distance azimuth velocity quality, adjacent velocity quality, physical characteristics Quality, to achieve comprehensive track quality assessment, and make decisions on track confirmation, track termination, and waiting for confirmation of temporary tracks. This method comprehensively evaluates the track quality, and can effectively reduce the number of false tracks under the condition of ensuring the start of the real target track.

Description

technical field [0001] The invention belongs to the technical field of radar data processing, in particular to a method for evaluating the initial comprehensive quality of a search radar track. Background technique [0002] According to its basic functional logic, radar data processing can be divided into: track initiation, point track-track correlation, track prediction, track filtering, and track termination. Dong Zhirong pointed out in his research that track initiation should refer to the track establishment process before entering stable tracking (track hold), which includes the selection of track head, track initial track segment and its The process of formation. In the multi-target dense environment, due to the inherent combination explosive characteristics of the track initiation method and the lack of target information before track initiation, the track initiation problem is considered to be the first difficult problem in radar data processing. In engineering pra...

Problems solved by technology

[0005] Existing methods for evaluating the initial quality of search radar tracks mainly evaluate the track quality from one or more aspects, and do not make full use of the current existing information, so they cannot fully evaluate the track quality of the initial track.
