摘要
详细分析了高速平动和旋转运动对空间目标一维成像的影响,建立了目标雷达回波多分量多项式相位信号(mc PPS)模型,采用基于多延迟乘积型高阶模糊函数(ml PHAF)的方法估计模型参数,并提出了两类不同稳定姿态的空间目标的运动补偿方法。仿真实验表明这两种方法对运动引起的成像失真有显著改善。
The influence of the translation and rotation on a space target is analyzed in detail and the radar echoes backscattered by a space target are modeled using multicomponent polynomial phase signal (mc-PPS) model. Two methods to compensate the motion of the space target are proposed based on multilag high order ambiguity function (ml-PHAF). The simulation shows that these two methods can remarkably improve the radar image deformed by target motion.
