摘　　要：传统的遗传算法在实现雷达海杂波反演蒸发波导剖面时呈现寻优速度慢,早熟收敛的现象,本文引入了具有更强寻优能力的免疫算法实现反演过程.阐述了免疫算法实现海杂波反演蒸发波导剖面的原理,根据反演问题特点对免疫算法进行了最佳参数选取的仿真,并分析了实现RFC(Refractivity from Clutter)中免疫算法相对于遗传算法的优势,最后采用我国某海域采集到的海杂波、探空、气象水文等数据对反演算法进行了检验,结果表明免疫算法较遗传算法更适用于解决海杂波反演蒸发波导剖面问题.In the process of inverting evaporation duct profile from radar clutter,traditional genetic algorithm presents a slow speed of seeking best parameters and premature convergence.In this paper,immune algorithm is used and realizes the inversion.The principle of immune algorithm is briefly described,and the procession of selecting the best parameters for the algorithm is emulated according to the characters of inversion question.The immune algorithm is compared with genetic algorithm and its advantage In RFC（Refractivity from Clutter） is analyzed.Finally,according to the sea clutter and hydrometeorological data collected from China Sea,the immune algorithm is tested（verified）.It is indicated that immune algorithm is better than genetic algorithm in solving the question of retrieving evaporation duct profile from sea clutter.
