Abstract
A method of suppressing the non-linear chirp interference with specific time-frequency structure is proposed according to the characteristics of matched signal transform(MST).The mean square error of pararmeters estimation based MST is analysed. The simulation results showed that this method can not only suppress nonlinear frequency modulation time-varying interference effectively, but improve the real time performance also.
