摘要：
A near space hypersonic target coherent integration algorithm based on multi-scale search compensation is proposed for the problem of range gate stride and Doppler extension. In order to complete the coherent integration, on the basis of range migration compensation, the estimated values of the target acceleration and second-order acceleration are searched simultaneously according to the change interval of the target acceleration and second-order acceleration. Then the multi-scale search method is used to solve the contradiction between the search scale and search calculation. The simulation results show that the proposed 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 traditional integration algorithms. © 2020, Editorial Dept. of JA. All right reserved.
