摘要
该文建立了多基站ISAR3维转动转台目标的成像模型和成像算法,同时分析了多基站ISAR3维转动转台目标的成像约束。通过在多基站ISAR3维转动转台目标成像模型的基础上构造多基站距离向投影方程组和方位向多普勒方程组,实现了同时对目标散射点位置参数和运动参数的估计。仿真实验验证了多基站ISAR平面转台模型成像算法。
In this paper,the multi-static ISAR three-dimension turntable model and imaging algorithm are proposed.Furthermore,the multi-static ISAR three-dimension turntable imaging constraints are analyzed.Based on the range projection equations and azimuth doppler equations deduced by multi-static ISAR three-dimension turntable model,the positions and movement parameters of target scattering points are obtained.The multi-static ISAR three-dimension turntable model and imaging method are verified with simulation experiments.
