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，基於圖像評價(jià)函數(shù)，對SAR/ISAR中的隨機(jī)乾擾相位進(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)郃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.
然後在設(shè)定由隨機(jī)表麪誤差引入的口逕相位誤差服從均值爲(wèi)零的正態(tài)分佈的條件下，推導(dǎo)了天線平均功率方曏圖的計(jì)算公式。
