摘要：
For the linear frequeney-modulated continuous wave radar, the coupling of fast time and slow time in the signal phase is occurred for the moving target detection, which results in migration through range cell in multi-cycle signal. A new processing method for moving target detection based on Keystone transform is proposed to solve above problem. Through the characteristics analysis of the received multi-cycle signal and utilizing the decoupling property of Keystone transform, a transform expression in the moving target detection processing, is derived which can be used for the range profiles alignment. Finally realization and performance of the proposed method is discussed. Compared with the direct motion compensation method, the efficiency of the proposed method and the relevant conclusion are verified by the simulation results.
