A Sorties Recognition Algorithm of Formation Targets for Wide-band Radar

摘要

Aiming at the disadvantage that conventional low resolution radar can't distinguish formation targets in range and azimuth, a sorties recognition algorithm of formation targets is proposed in wide-band radar, which is based on image processing technology and signal detection theory. The Smaller of Constant False Alarm Rate (SO-CFAR) and sliding window detection are used to cluster the targets of different sorties, and eliminate the interference of clutter and noise on sorties recognition. In addition, the connected region labeling technique is carried out to realize the automatic recognition of sorties in formation targets. The experimental results of some measured data illustrate the effectiveness of the proposed method.
