In this paper,the principle of pulse compression based on linear frequency modulation is described,and the effect of pulse compression is simulated and analyzed. Some technical elements such as waveform-parameter setting and the matching filter designing with window function are analyzed emphatically. It is presented that the algorithm frame of target signal detecting and taget information extracting for missile-borne Radar using pulse compression based on linear frequency modulation. The practical application indicates that putting to use the technique of pulse compression based on linear frequency modulation,ensures missile-borne Radar to have high range-resolution detecting capacity,and exalts target detection ability and anti-jamming capability of missile-borned Radar guidance system in the complex battleground electromagnetic environment.
