A method of designing the group delay filter is proposed in this paper.Firstly,two linear frequency modulation signals is cascaded.Then the reference signal is delayed,finally,the group delay filter cofficients are obtained by fourier transform.The non-causal FIR filter designed by this method has the advantage of accuracy and low complexity.Computer simulation shows the performance of this method,is good.
