摘要/Abstract

摘要： 从功率谱角度分析了数字射频存贮器(DRFM)信号重构的性能，绐出了分析方法和典型雷达信号的分析结果。通过计算仿真，得出了零阶保持信号归ー化能量随中心频率变化情况。还给出减小零阶保持产生信号失真方法，并给出补偿滤波器的传递函数。

Abstract: From the point of view of power spectrum, the paper analyses the signal rebuilding per?formance of a digital RF memory (DRFM)，and presents the method of analysis and the results of typical radar signals. The paper also presents a method of reducing signal distortion with the appro?priate compensating filter, and plots the variation of normalized energy of zero-order hold signal ver?sus the center frequency of down-conversion through computer simulation.

Key words: signal rebuilding , digital RF memory , DAC , power-density spectrum
