摘　　要：针对高速运动目标相位编码回波信号不能进行长时间相参积累,提出双频共轭处理方法,该方法采用双频共轭及Keystone变换处理,同时解决高速运动目标越距离单元走动及速度模糊,实现信号的有效相参积累。采用两目标回波仿真数据进行实验,实验结果表明了该方法的有效性。Since the phase-coded echo signal of high-velocity moving target can＇t be long-term coherent integration, a method of double-frequency conjugate processing is proposed in this paper, in which the double-frequency conjugate processing and Keystone transform are adopted to solve the range migration and velocity ambiguity of high-velocity moving target simultaneously and realize effective coherent integration. The two targets echo simulation signals were used in experiment. The experimental re- suits indicate that the method is effective.
