random phase error

基本解释

This paper proposes a progressive approach algorithm based on image cost function to compensate the random phase error in SAR/ISAR imagery.
本文提出逐级逼近算法，基于图像评价函数，对SAR/ISAR中的随机干扰相位进行补偿。
Triggering time synchronization error model is derived, and based on phase noise model of frequency source, random synchronization error is considered.
本文建立了触发时间同步误差模型，结合频率源相位噪声模型，初步分析了随机型时间同步误差对成像的影响。
Secondly, on the assumption that the phase error on the aperture led by the random surface error obeys the Gaussian distribution with zero mean, the expression of the average power pattern is deduced.
然后在设定由随机表面误差引入的口径相位误差服从均值为零的正态分布的条件下，推导了天线平均功率方向图的计算公式。
