Radar clutter frequency spectrum characteristic simulation system based on reverberation chamber and method thereof

The invention discloses a radar clutter frequency spectrum characteristic simulation system based on a reverberation chamber and a method thereof. The invention relates to the technical field of a detecting method for positioning or existence of reflection or re-radiation of radio wave. The method comprises the following steps of performing mathematical modeling on a low-sea-condition sea clutter spectrum by means of an Allpole model, and performing mathematical modeling on a high-sea-condition sea clutter spectrum by means of a combined Exponential model; changing rate of a stirrer and repeatedly acquiring a plurality of sets of single-time sampling signals Ssample of the two spectrum models; performing Fourier transform and normalization processing on the obtained single-time sampling data, and analyzing the frequency spectrum characteristic. The method realizes finer and more accurate simulation for the frequency spectrum characteristic of the radar clutter. 本发明公开了种基于混响室的雷达杂波频谱特性模拟系统及方法，涉及采用无线电波的反射或再辐射的定位或
