Two kinds of normal working waveforms of pulse Doppler radar are introduced and analyzed in this paper,and the quasi-continuous wave modulated signal is studied in detail,then an effective anti-eclipse method under high-PRF is proposed.Also the linear frequency modulated waveform commonly used in radar seeker is analyzed,then the signal functions and the flow charts of signal process are given,and the signal parameters are analyzed.Based on these methods and the development trend of the radar seeker,the design concept for multiple working waveforms system is presented to give the reference for the working waveform practicality design of the radar seeker.
