摘　　要：建立了匀角速度平面转动目标和匀角加速度平面转动目标的多基站ISAR平面转台目标模型,给出了多基站ISAR平面转台目标的成像算法,同时分析了多基站ISAR平面转台目标成像约束。通过在多基站ISAR平面转台目标成像模型的基础上构造多基站方位向多普勒方程组和距离向投影方程组,实现了对目标散射点位置参数和运动参数的准确估计。仿真实验验证了多基站ISAR平面转台模型和成像算法。The uniform angular speed and uniform angular acceleration rotational target multi-static ISAR two-dimension turntable models and imaging algorithms were proposed respectively.Furthermore,multi-static ISAR two-dimension turntable imaging constraints were analyzed.Based on the azimuth Doppler equations and range direction projection equations deduced by multi-static ISAR two-dimension turntable model,the positions and movement parameters of target scatters were obtained.The multi-static ISAR two-dimension turntable model and imaging method were verified by simulation experiments.
