摘要
噪声中的指数衰减信号的极点提取方法在目标识别等领域具有非常重要的地位。文章给出利用遗传算法提取指数衰减信号极点的方法。通过实验表明,该方法较其它方法简单有效,即使在较低信噪比的情况下,也能对极点作出较好的估计。
Pole extraction of contaminated damped exponential signals is very important in many fields such as target recognition.In this paper,a pole extraction method based on genetic algorithm is presented.The experimental results demonstrate that the method can give a better estimation of poles of damped exponential signals even in a lower sig-nal-to-noise ratio(SNR)situation.
