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 phaseerror 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.
The analytical expressions of the error spectra caused by random errors in the measurement of amplitude and phase of the near field in planar near field measurements are presented.
