A near‐space hypersonic target coherent integration algorithm based on search compensation is proposed for the problem of range gate stride and Doppler extension. The algorithm first estimates the target radial velocity and Doppler rate by searching, and then completes coherent integration of echo signal via distance and phase compensation according to the estimated values. The simulation results show that the algorithm can effectively solve the problem of range gate stride and Doppler extension, suppress noise, and increase gain. The integration effect of the proposed algorithm is obviously superior to the classical moving target detection (MTD) algorithm.
