把高速数字信号处理器(DSP)用于雷达的杂波模拟是一项很有前景、且正在被广泛应用的技术。文中从雷达杂波的分布特性出发,分析了低分辨率雷达的地物杂波的幅度概率密度分布和功率谱分布特性。并建立了一种有效的快捷的杂波模拟算法模型,以ADSP-TS101S为核心,设计完成了采用并行处理结构的一种雷达杂波实时模拟系统。

Simulation of the radar clutter by using a high speed digital signal processor is a technology that is perspective and is being used widely. The distribution characteristic of the radar clutter is used to analyze the probability density and the power spectral density of the low resolution radar. An effective and fast way to simulate clutter echo is put forward on basis of the knowledge and by using ADSP-TS101S,a complete system with parallel structure is designed for clutter echo simulation.
