Separation Method of Radar Signals in the Complex Electromagnetic Environment

Under the complex electromagnetic environment,the radar examination ability which is further enhanced is one of the modern radar facing urgent problems.In order to improve the radar surveying precision,it is necessary to withdraw the radar signal effectively from the multitudinous unwanted signals.In view of the even more obvious limitation of the convention radar signal processing methods,one kind of the signal blind source separation method based on the greatest signal-to-noise ratio is proposed.First using the characteristic of bigger and better signal-to-noise ratio the separation effect,the signal-to-noise ratio objective function is established,then the blind signal separation optimized matrix is obtained through the solution of the objective function,finally the radar blind signal separation is realized.The simulation result indicates that this method may carry on the effective separation to the radar blind signal without any priori knowledge which other signal processing methods request to take the condition.
