摘要
从理论上分析了脉内调频脉间步进跳频(LFM-SF)雷达信号的频谱特性,对子脉冲带宽与脉间步进频率间隔的关系对合成信号频谱分布的影响进行了深入研究,对频谱分布特性进行了仿真,为LFM-SF体制宽带雷达的调频带宽选择提供了坚实的理论实践依据,最后给出了LFM-SF信号处理过程。
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.
