The detection performance of radar maneuvering target with jerk motion is affected by the range migration (RM) and Doppler frequency migration (DFM). To address these problems, a fast algorithm without searching target's motion parameters is proposed. In this algorithm, the second-order keystone transform is first applied to eliminate the quadratic coupling between the range frequency and slow time...
The detection and motion parameter estimation performance of a high-speed maneuvering target with a fixed acceleration is affected by the range migration (RM) and Doppler frequency migration (DFM). To address these problems, a fast non-searching algorithm is proposed. Firstly, the second-order keystone transform (SKT) is applied to remove the quadratic coupling between the range frequency and slow-time...
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...
