建立了高速导弹导引头雷达的目标回波模型，简述了一种新的Chirp-FFT信号处理方法，介绍了最小波形熵原理，同时介绍了一种新的算法——免疫克隆选择算法。免疫克隆选择算法是一种快速且保证收敛到最优的智能搜索算法，把它与最小熵原理结合作为准则来实现二维参数的搜索。结果表明，将它应用于雷达的参数搜索中，既达到了雷达的高分辨处理，又很好地解决了二维搜索时的计算量大的问题。

In this paper, the target echo model of a high-speed missile is established, and a novel method of signal processing called chirp-FFT is discussed. The minimum-entropy criterion is introduced. An intelligent algorithm called Immune Clone Selection Algorithm (ICSA) with fast speed and convergence to the best solution is discussed. ICSA and the minimum-entropy criterion are fused to search two-dimensional parameters. This algorithm reduces significantly computational load while keeping high-resolution performance.
