| Abstract: | The spectrum performance of LFM-Subpulse (Linear Frequency Modulation) stepped frequency (LFM-SF) radar signal is analyzed. The effect of the relationship between the spectrum width of LFM-subpulse and frequency step size on distribution of synthesized signal is researched. Then, the simulations of the effect are given, and that supply the theoretic and practical foundation for the selection of frequency modulated width. In the end, the LFM-SF processing is discussed. |
