摘要
首先推导了特定海情下海杂波的平均雷达截面积,然后讨论了海杂波的幅度起伏模型,并给出了一种产生服从对数正态分布随机序列的算法。海杂波的功率谱模拟通常采用的是高斯模型,这与实际情况有所出入,所以采用频域取样法对模拟序列进一步处理,产生即具有特定概率分布,又具有所要求的功率谱的海杂波模拟序列。
This paper first deduces the average RCS of sea clutter, then discusses some kinds of amplitude distribution models and presents an algorithm of generate Log - Normal distribution stochastic sequence. Gaussian model usually used in power spectrum simulation, here use frequency domain sampling method to get sea clutter simulant sequence according to wants,
