| Abstract: | Stepped frequency radar is a very important type of the high range resolution radar system. The key problems of the stepped frequency radar are discussed in this paper, including the waveform design, the algorithms of target extraction, the processing of Modulated Frequency Stepped Radar Signal, and the compatibility between stepped frequency radar and conical scan radar. In each situation, the Doppler effects are analyzed. And some processing schemes are given. |
