针对机载脉冲多普勒雷达长时间相参积累时，空空目标在距离维上走动引起的相参积累能量损失问题，提出了在距离频域按照目标径向速度进行线性相位补偿的方法，实现目标的距离走动补偿。理论分析和仿真实验表明，该算法能把不同时刻目标回波校正到同一距离单元，有效的提高了目标的相参积累能量，且算法复杂度不高，并已在雷达实际试飞中得到了运用。

Air-to-air targets in range dimension migration cause the energy loss in airborne pulse Doppler radar long time coherent accumu-lation. In view of this problem, a linear phase compensation method in accordance with the target radial velocity was used to realize the range migration compensation. Theoretical analysis and simulation results show that the algorithm can correct different moment target echoes to the same range unit, effectively increases the target coherent accumulation energy with lower complexity, and has been used in actual flight experiment of radar.
