| Abstract: | The random noise ultra-wideband radar signal was analyzed and its power spectral function was also given.Through the theoretical analysis and computer simulation,the statistical peak sidelobe level(PSL) of compression wave of the correlation receiver,and the resolved ability were studied.The simulation result shows that this signal possesses lower PSL better resolved ability in comparison with the LFM ultra-wideband radar signal on a certain condition. |

| Keywords: | radar engineering random noise ultra-wideband radar signal peak sidelobe level resolved ability |
