| Abstract: | Orthogonal transformation and pulse compression are two basic technologies in radar signal processing.In this paper,it introduces the basic principles of orthogonal transformation and pulse compression,and realizes successively the two processes to LFM signal based on Matlab.It comes down to the selections of sampling frequency,matching filter and side petal restraint in pulse compression processing,provides the computer simulations.The results prove that pulse compression can improve the distance resdution. |
