Study on Wideband LFMCW Radar Echo Signal Simulate Technique

摘要

An wideband LFMCW radar echo signal simulator design scheme which is based on Agilent N8241A arbitrary waveform generators and E8267D vector signal generator is designed. In this scheme, the radar signal wave data is produced by computer, and is changed to wideband IQ baseband signal by N8241A. Then, the baseband signal is inputted to Agilent E8267D, which switch the baseband signal to microwave radio signal by its IQ modulate function and output, for testing wideband LFMCW radar in lab. Experiment result indicate that the simulator possess not only wide using performance and high precision, but also have simplify structure.
