摘要

Microwave receive system is used in many fields, such as communication, radar, space technique. Receive system sensitivity's measurement is very difficult because of broadband and high frequency. The general receive system sensitivity measuring Instrument designed by ourselves based on PXI bus computer, virtual-instrument card and drive software can complete the sensitivity measurement to many kinds of receive systems. This paper providers the working theory, hardware structure, software design and the sensitivity measurement example of radar receiver.
