PROCESSING OF MULTI-TARGET DATA FOR MULTI-CHANNEL PASSIVE RADARS

摘要

The present invention relates to the general field of the tracking radar applied to systems multistatic radar. It consists of a method making it possible to merge in a coherent manner, the elementary tracks made on the basis of the different bases bistatic constituting the system so as to create and maintain the tracks of a manner such that an object detected by a single base bistatic is represented by the corresponding track and that an object detected by several bases bistatic and giving rise to the creation of a plurality of elementary tracks is shown as a single overall. The melting of an elementary strip with a track or that of two elementary strips to form a track overall is based on the estimation of a statistical distance for separating a track overall i and an elementary path j of a base bistatic b, the calculation of being carried out on the basis of the components distance bistatic bistatic speed and the azimuth end of the elementary track candidate to the combination and the projection of the condition x of the strip within the base of the candidate bistatic elementary.
