Achieving Target Identification for the MMW Seeker based on Scanning Matching and Beam Pointing

Focusing on the problem of target recognition in complex land backgrounds, a target identification method using scanning correlation and beam pointing is proposed in this paper. Considering the complex scattering characteristics of ground clutters, correlation thresholds associated with range and angles are set to eliminate false targets. Firstly, seeker scanning is implemented twice from left to right, then from right to left to eliminate the negative influences of ground clutters. The information of the detected targets during scanning including range and angles are stored. Point or body identification is realized based on the high-resolution range profile (HRRP). Finally, error distribution area is calculated by combining with the beam pointing information from the fire control system. Target identification is realized by finding the nearest target.
