Abstract: A method of multiple parameters estimation for multiple chirp signals is proposed,a brief performance analysis is also described.Compared with references,the computational load of the method is more attractive,it is favorable to realize for real-time.It is no need for multiple-dimensions search.The results of simulation show that the method can accurately estimate multiple parameters of multiple chirp signals under the lower ratio of signals-to-noise. -
