This Letter addresses the coherent integration problem for air and space moving target detection in a staggered pulse repetition interval (PRI) radar system. In this algorithm, a range‐compressed signal is firstly transformed into the one in the range frequency domain, and then the authors resample the non‐uniformly sampled signal into a uniform grid along azimuth direction. Subsequently, the well‐known Keystone transform is applied to compensate the range cell migration caused by target motion. Finally, a moving target can be well focused in the range‐Doppler domain after motion compensation. Simulated results are provided to validate the effectiveness of the proposed algorithm.
