| Abstract: | Owing to its good anti-jamming capability and the property of low probability of intercept,the phase-coding signal is widely applied in radar waveform generation. This paper gives out the characteristics of phase-coding signal in time-domain and frequency-domain, analyzes the signal characteristics by means of the fuzzy function and finds that the signal has high resolution of the distance and the velocity, analyzes the process and result of this kind of signal being matched filtering compressed, discusses the design of the time-domain side-lobe suppression filter adopting phase-coding signal with large time-band width product, and provides the engineering realization method. |
