Abstract

Three consecutive algorithms are used to estimate the number of multiple overlapped pulsed received chirp signals and their parameters in the electronic support measures (ESM) station noisy receiving window at low signal to noise ratio. The first consecutive algorithm is used to estimate both the number of multiple overlapped received radar signals and the chirp rate of each one in the receiving window. Then, the second consecutive algorithm is used to minimize the additive noise and/or interference in the receiving window by filtering each received chirp signal in the corresponding fractional Fourier domain. The third consecutive algorithm based on WD and Hough transform is used to estimate both the received chirp signal duration and the received chirp signal bandwidth.
