| 摘 要： | 针对逆合成孔径雷达(ISAR)的小转角目标回波特点,提出通过快速生成包络和相位的方法来构成目标回波.根据ISAR的成像原理,忽略包络延迟中由转动生成的分量和相位变化的弱小分量,降低了计算复杂度.对于由多个散射点构成的机动目标,只加入影响较大的偏航运动,运算量得以减小.模拟机动目标回波的成像结果证明了该方法的有效性.

| Abstract: | To consider the echoes' characteristic of the moving target with small angle for inverse synthetic radar(ISAR),the target's echoes are simulated by generating the envelope and phase quickly.Based on the principle of ISAR imaging,the rotation part in the envelope and unimportant part in the phase are neglected,so that the computation complexity is reduced.For the moving target composed of scatters,the yaw motion is only considered in the simulation for its influence in the result is more significant,so that ... |
