LFM信号脉冲压缩三种结果及其统一表示

Three results of pulse compression for LFM signal and their unified representation

针对文献中LFM信号脉冲压缩输出结果表示不统一问题,首先给出了LFM信号脉冲压缩结果的三种典型表示形式;然后利用频域相乘法实现原理,导出了其统一脉冲压缩结果的表达式;最后分析了该统一表达式与三种典型结果的关系及变换条件,并通过仿真实验证实了本文理论结果和分析的正确性.

In view of the inconsistency of the output results of pulse compression for the linear frequency modulation（LFM） signal in the literature, this paper gives three typical expressions of LFM signal pulse compression results, and then uses the principle of frequency domain phase multiplication to derive its expression of uniform pulse compression results. Finally, the paper analyzes the relationship between the unified expression and the three typical results and the transformation conditions. The simulation results verify the correctness of the proposed theory and analysis.
