Study on ship-formation detection by missile-borne radar using DBS imaging algorithm

For moving ship-formation target, problems such as the appearance of virtual targets occurs if general DBS procedure was adopted for detection. This paper improves DBS realization method accordingly: to estimate the whole velocity of ship-formation target first, and then carve up azimuth direction Doppler basing on both this velocity and the velocity of the missile. Researches are made of ship target models, and the results prove the effectiveness of procedure.
