摘　　要：为研究数字射频存贮器 (DRFM )的幅度量化误差性能及对系统的影响 ,本文从典型雷达信号量化过程入手 ,通过分析对比有限精度量化和无限精度量化的带内信号能量和寄生信号能量 ,得到了DRFM量化误差性能的一些规律和定量的分析结果。这将为DRFM设计、选择或性能分析提供了一些依据以及计算和分析方法。In order to study the quantization error performance of the amplitude digital RF memory (DRFM) and the effect on the system, the paper analyzes and compares the signal-band energy and the spur energy of the limited resolution quantization with those from unlimited resolution quantization from the point of the quantization process of a typical radar signal. Some rules and results of computation for the quantization error of the DRFMs are found. The results will be helpful in the design, selection and analysis of DRFMs.
