This paper deals with the coherent radar detection with non-uniform pulse repetition intervals (PRI), which has strong electronic counter-countermeasures capabilities to enemy jammer thanks to its low interception and difficult to sort. A novel coherent processing framework for the non-uniform PRI returns is proposed to detect moving targets by exploiting the PRI relationship of the transmitting time sequences. It can achieve the range and velocity measurement without ambiguity. In addition, the optimized weighted window in the Doppler domain is designed to suppress the sidelobe levels which is introduced by the non-uniform PRI sequences. Finally, several simulation results are provided and discussed.
