海南发射场雷达测控设备工作时面临着较严重的海杂波影响，为此需要建立准确的海杂波模型，研究和掌握海杂波的性质。研究了球不变随机过程法(SIRP)产生相参相关 K 分布海杂波的仿真模型；其中，采用了基于复倒谱的方法来产生相关高斯随机序列；最后，开展了仿真实验。结果表明，本方法模拟产生的海杂波在概率分布和功率谱特性上与理论值都吻合，说明该方法是准确和有效的。该方法对开展海杂波条件下测控雷达检测性能研究和杂波抑制方法研究都有重要意义。

Sea clutters impact seriously on the performance of telemetry and control radars in Hainan launch site.There-fore,it is necessary to establish a correct mathematical model to research the characteristics of the sea clutters.The sim-ulation model for generating coherent correlated K-distributed sea clutters based on SIRP is researched,and the correla-ted Gaussian series are generated by a method based on the complex cestrum technology.Finally,the coherent correlated K-distributed sea clutters are generated by computer simulations.Results show that the probability distribution and the power spectrum density of the simulated sea clutters match well with the expected theoretical results,which proves that the method is correct and valid.The proposed method will benefit researches on radar detection performance analysis and clutter suppression technologies.
