The invention discloses a method for evaluating the comprehensive quality of search radar track initiation, and belongs to the technical field of radar data processing track initiation. Aiming at the problems of suppressing false tracks and improving the track initiation accuracy in the radar data processing track initiation process, the method comprehensively uses elevation fluctuation condition quality, elevation quality, off-axis angle quality, distance same quality, Doppler channel number quality, Doppler goodness of fit quality, amplitude quality, correlation point number quality, clutter map quality, environment perception quality, correlation probability quality calculation, distance residual quality, distance azimuth velocity quality, adjacent velocity quality, and physical characteristic quality to realize comprehensive track quality evaluation, and decisions of track confirmation, track termination and confirmation waiting are carried out on a temporary track. According to the method, the track quality is comprehensively evaluated, and the number of false tracks can be effectively reduced under the condition that the real target track initiation condition is ensured.
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...
