M2M4信噪比估计算法的统计性能分析
Statistical Performance Analysis of the M2M4 Based SNR Estimator
摘要
Abstract
The statistic performance evaluation of signal to noise ratio (SNR) estimation in radar signal processing is discussed , which focused on the second moment and fourth moment ( M2 M4 ) based estimator. With the help of first-order Taylor approximation , the root mean square error of the algorithm is derived in approximately closed form solution which gave its, relationship with the length of observed data and SNR. Computer simulation results show that the approximate formula for the Normal signal (NS) , linear FM signal ( LFM) are consistent with the simulated results in a certain SNR range.关键词
