Analysis and Design of Microwave Virtual Time-Frequency Analyzer

摘要

In this paper, the main shortages of the classical signal processing are indicated firstly, and then a design scheme of microwave virtual time-frequency analyzer based on virtual oscilloscope and virtual spectrum analyzer is presented. The function of the presented virtual instrument (Ⅵ) is described simply, the design of software and hardware of the developed instrument is expatiated upon emphatically, and in the end the key-technology of the design is discussed.
