现代雷达杂波模拟的一些新方法

Some New Methods of Clutter Simulation for Modern Radars

基于提出的参差周期预测插值和IIR滤波理论，本文研究了具有脉间参差周期特性的雷达杂波模拟方法．通过分析脉冲压缩杂波的生成机理，对相位编码和线性调频的脉压雷达杂波的模拟方法也进行了研究．最后，对在平稳和非平稳区中具有综合技术的现代雷达杂波模拟的方法进行了讨论．

Based on the presented theories of stagger-period prediotive interpolation and stagger-period IIR fil tering, this paper studies simulation methods of radar clutter with stagger-interpulse-period nature. By analysing the production mechanism of pulse compression clutter, simulation methods of rader clutter with pulse compressin of phase-coded and linear FM are studied, too. Finally, simulation methods of clutter of modern ra dars with multiple techniques and in stationary and nonstationary regions are discussed
