Abstract In order to solve the problem of recognition to the ground-based radar station using an active radar seeker, the fusion recognition algorithms are put forward. Firstly the electromagnetic scattering model of the phased-array antenna is established. Then using Doppler Beam Sharpening (DBS) technology to improve the detection probability and to estimate targets’ RCS, then based on the extracted features－the range property and the period property of RCS, four kinds of characteristics of phased-array radar antenna are constituted. Finally the recognition algorithms as well as the fusion technique for target recognition are put forward. The simulation experiment indicated the effectiveness of the algorithm.
