This paper deals with the problems of detecting a chirp signal of motion target against a strong leakage signal from transmitter in radar. The Generalized Almost-Cyclostationary (GACS) signal processing method was utilized to determine the detection of motion target and extract feature of the chirp signal from the target. This techinque which exploits second order cyclostationary to detect features of the chirp signal in low SNR has desirable properties. The study utilized a method to determine and chracterize signals for highly adverse signal to interference pluse noise and explain how using cyclostationary properties can extract feature of chirp signal from the mixture received signal. Finally, those theories and simulations that are in better harmony indicate the efficiency of the method in the detection.
