摘要：

In allusion to the coupling relationship among radial velocity variation, range migration and Doppler spread of a maneuvering target, a dynamic programming (DP) based long time coherent integration (DPCI) detection method is proposed. The energy of the target of high velocity and strong maneuver could be integrated along its trajectory by the proposed DPCI method with high efficiency. The main idea of the DPCI is the joint execution of two operations: the modified DP procedure that could search the current position and velocity of the target, and the improved coherent integration that could calibrate the Doppler shift during the entire process with any large phase spread. The proposed method is applicable to a target with arbitrary motion without estimating its specific movement parameters. Simulation results and performance comparisons show the accuracy and superiority of the proposed method. (C) 2017 Elsevier GmbH. All rights reserved.
