摘要 现有的基于前向阵雷达的SAR-GMTI方法主要是空时自适应处理(STAP),而STAP在实际工程中难以实现。针对这一情况,该文提出了一种基于机载前向阵雷达的斜视SAR-GMTI新方法。文中建立了基于前向阵雷达的三通道斜视SAR-GMTI体制下的运动目标回波信号模型,利用等效分析建立了该模型与传统三通道相位中心偏置天线(DPCA)模型的联系。通过改进的DPCA技术,实现该体制下的动目标检测、测速和定位。最后仿真结果验证了改进的DPCA技术的有效性。 Available SAR-Ground Moving Target Indication(SAR-GMTI) method based on the forward-looking antenna is mainly Space-Time Adaptive Processing(STAP),which is hard to be practically realized.For this fact,an advanced SAR-GMTI method based on the forward-looking airborne radar is proposed in this paper.This paper establishes the echo model of moving targets,and illustrates the connection between the traditional Displaced Phase Center Antenna(DPCA) systems and this proposed system.The improved DPCA technology is presented for moving target detection,location and velocity measurement.Finally,the simulation results confirm the effectiveness of the improved DPCA technology.
