MM-wave High Linear FMCW Generator and Distance Measurement Experiment

摘要

The paper dicribles a high linearity and fast scan FMCW generator, including its structure, performance , analysis and the experiment results of distance measurement experiment.rnThere are several merits in MM-wave band, such as wide available bandwidth, small antenna dimension. So it has a wild application prospect in position determing technique. Recently, because the needs of accuracy missile guidance technique in military use and vehicle collision warning technique in civilian use, there are a lot of report on the MM-wave radar, especially on MM-wave LFMCW radar techniques[ 1,2]. FMCW radar has very excellent characteristics especially in accuracy, anti-interference, small power and so on.
