Abstract
Range migration and Doppler spread are the two basic and troublesome problems in moving target detection during long integration period. In this paper, a narrowband detection method for multiple high speed targets which effectively solve the two problems above is proposed. The proposed method utilizes keystone transform (KT) to correct range migration, and Doppler spread is compensated according to the target radial acceleration which is accurately estimated by the combination of cyclic auto-correlation detection algorithm and "Dechirping" method, then, coherent integration is implemented for target detection. The new algorithm has many advantages including improved detection performance, an effective solution to range migration and Doppler spread, extended observable coherent integration time (CIT), precise estimation of the target moving parameters and less computation costs. Its performance and computer simulations are analyzed at end of this paper. The simulation results demonstrate the superiority and validity of the proposed algorithm. (5 pages)
