摘　　要：文中首先分析了基于相位中心偏置天线(DPCA)技术的SAR动目标检测原理,然后详细介绍了基于该原理建立的一种新的双天线动目标检测模型。该模型能在检测出动目标的同时精确估计出动目标的运动参数。最后通过将真实的雷达图像和模拟运动点目标合成的数据,验证了模型的正确性和有效性。此模型易于实现,运算量小,适合运用于现代雷达系统。The SAR motion target detection theory based on the Display Phase Center Antenna （DPCA） technology was analyzed in this paper firstly. Then according to this theory, a new mode was introduced, which could not only detect motion target, but also evaluate motion parameters of motion exactly. Finally, add motion point target data on real radar data to form simulating data, test the mode with these data could prove it feasible and valid. The mode could be realized easily and need small computation, which makes its fits for modern radar system.
