The Analysis And Simulation Research of Distance Resolution and Ambiguity Property of LFM Signal

The linear frequency modulation signal with bigger time-bandwidth product which is widely used in the pulse compression system radar. This paper is according to characteristic of the linear frequency modulation signal, and use the ambiguity function theory to analyse the characteristic. Gave out the course and result of the linear frequency modulation signal through matched filter. Hamming weighting the matched filter output response and simulation the output signal through weighting, and analyses the influence of window function to the matched filter output response and the distance resolution .
