盲信号分离是近几年才发展起来的,用于解决从混合观测数据中分离源信号的一门新技术,已在众多领域中获得了广泛的应用。文中结合高阶累积量对高斯噪声的不敏感性,给出了一种基于盲源分离的雷达信号分选方法,可以对高斯噪声背景中混合的多个雷达信号实现分选。最后给出了该方法的计算机仿真,结果证明了该方法的有效性。

Blind source separation is a new technique that has been developed greatly in recent years.it is used to recover source signals from their mixtures.As a new technique,it has been applied in many fields.By the fact that high order cumulant is insensitive to white Gaussian noise,we give out a method for selecting radar signals based on blind source separation in this paper,This method can select radar signal from the mixture of multiple signal in white Gaussian noise context.At last,the simulation for this method is given in this paper.Simulation result have shown the validity of this method.
