摘要
最初的测速雷达是采用FFT进行信号处理的,效果不够理想.为此,用PPS信号建立了测速雷达回波信号的数学模型,采用Radon-STFT方法对多个多项式相位信号进行检测.结合“CLEAN”技术,实现对多个多项式相位信号进行分离和参数估计,得到了令人满意的结果,是一种有效的算法.
Doppler speed radar is a substitute of Doppler velocimeter, and it has been widely applied to artillery army. The old speed radar processes signals with FFT, but the result is not satisfied. This paper builds the mathematical model of echo signals, and introduces the method of multi-polynomial phase signals detection using Radon- STFT. Combined with CLEAN technique,the method can be used to multi-polynomial phase signals separation and parameter estimation and gives the satisfied result. It is an effective method.
