random phase error

基本解釋

This paper proposes a progressive approach algorithm based on image cost function to compensate the random phase error in SAR/ISAR imagery.
本文提出逐級(jí)逼近算法，基于圖像評(píng)價(jià)函數(shù)，對(duì)SAR/ISAR中的隨機(jī)干擾相位進(jìn)行補(bǔ)償。
Triggering time synchronization error model is derived, and based on phase noise model of frequency source, random synchronization error is considered.
本文建立了觸發(fā)時(shí)間同步誤差模型，結(jié)合頻率源相位噪聲模型，初步分析了隨機(jī)型時(shí)間同步誤差對(duì)成像的影響。
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.
然后在設(shè)定由隨機(jī)表面誤差引入的口徑相位誤差服從均值為零的正態(tài)分布的條件下，推導(dǎo)了天線平均功率方向圖的計(jì)算公式。
