摘要
Abstract
Pulse compression technology can effectively solve the contradiction between the radar range and resolution,which has been widely used in radar system.According to the classical theory explanation, the radar signal which has pulse compression property has large time-bandwidth product.For the different forms,there are different pulse compression outputs of the same target.Under the MATLAB simulation en-vironment,this thesis studies and compares two kinds of radar signal-linear frequency modulated(LFM) signal and hyperbolic frequency modulated(HFM)signal.It analyzes the difference between the pulse com-pression performances of the two kinds of signal respectively from the perspectives of time-frequency charac-teristics,the instantaneous frequency difference of transmitting and receiving signals,the pulse compression outputs of static and moving target echoes,and Doppler time-varying properties.关键词
