N2 - The coherent integration of multiple pulses can improve the detection performance of weak targets. However, in the process of coherent integration, serious echo envelope migration exists when the target moves fast. A method named keystone transform has been proposed to solve this problem. Nevertheless, for wideband radars, the problem of energy dispersal increases the difficulties of Doppler ambiguity searching. Thus, in this paper, a Doppler ambiguity searching method based on energy accumulation is proposed. The effectiveness of the algorithm is verified by the simulations.
