Abstract
The main function of Radar is detect the target of remote through analyse the signal of returning. We need process the the signal of returning because of it containing lots of the other signal.Then we can separate the useful signal and the useful information.
This article include two main problem,the one is that separating the signal of FMICW which mix with many different frequenzes,the other is that geting the information of time delay from the signal separated.When we solve the first problem,we process the signal with the measure of quadrature transforming and filter, and then we separate the signal. Then we make the signal separated Fourier Transform, and we can get the information of time delay from the frequency spectrum.When we analyzing and solving the problems ,Digtial signal process is the base,and the idea of SR is the measure of solving problem.At last ,we can simulate with the tool of Matlab.
Key words: FMICW(Frequency Modulated Interrupted Continuous Wave),quadrature transform, Fourier Transform
