Coherent radars have multiple applications; among them, they can obtain multiple pulses and improve the radar detection ability with the help of coherent integration technique. However, the coherent integration performance can be greatly influenced by the range migration (RM), and Doppler frequency migration (DFM) effects for the highly maneuvering targets. In this paper, a fast non-searching method based on adjacent correlation ACF) and Lv's transform (LT), is proposed to realize the coherent integration for a maneuvering target. In particular, it first employs the ACF to correct the RM and reduce the order of DFM. Then, the coherent integration is obtained via LT. The advantage of the presented method is that it can achieve the coherent integration without any searching procedure, and thus the computational cost is reduced significantly. Finally, the simulations are provided to demonstrate the effectiveness.
