摘要： 分析了随机海浪空间特征量的研究现状和合成孔径雷达(synthetic aperture radar, SAR)海面成像机理.采用线性叠加法模拟波面得到波峰的空间形态，提取出波峰长度信息并进行统计分析.SAR观测得到的波峰长度的统计分布与数值模拟结果比较表明两者符合较好，从而验证了数值模拟技术的有效性.同时，给出大型海上结构物遭遇某一长度波浪的概率公式.

Abstract: The progress in the research of the statistical distribution of wave crest characteristics and the mechanism of synthetic aperture radar (SAR) wave image were reviewed in this paper, and the information of crest length were obtained by applying the linear accumulative method to the simulation of random wave crest. The comparison of crest length distribution shows there is a goodness of fit between numerical simulation and the observation of SAR. It validates the technique of numerical simulation and deduces a probability equation of crest above certain length.
