| Abstract: | The contraction between the radar detection range and range resolution has been effec-tively resolved by pulsecompression（PC）signals,so the PC signals are widely used in various mechanism radars.Two common PC signals——linear frequency modulation signal and phase-coded signal,are studied in this paper,and the differences of two PC signals are analyzed from the aspects of time-frequency domain characteristics,pulse-compression process and ambiguity function. |

| Keywords: | pulse-compression signal linear frequency modulation signal phase-coded signal ambiguity function |
