| Abstract: | The physics meaning for the laser radar cross section is discussed. The principle for contrast measurement at present engineering application is analyzed. The measurement problems in large target measured project are pointed out. Based on laser radar scattering section equation and the physics definition, two theoretic methods and together with ideas are put forward. The conclusion could be used as referenced to measure the LRCS of large target. |
