Experimental and theoretic study on laser radar cross section of the cooperative targets with 1″order corner reflectors

Under the radiation of 1.06μm laser beam,the Laser Radar Cross Sec-tion(LRCS)of 1″order corner reflectors have been investigated between-50°～50°azimuth angle when elevation angle is 0°,and the LRCS of the ladder-shaped coopera-tive targets combined with corner reflectors have been measured from-64°～64°azimuth angle as elevation angle range varing from 0°～24°by using LRCS measuring system.The angular resolution is 1°.The measured data are reported.The experimen-tal results are in agreement with the theoretical estimate.It indicates that increasing signal intensity and expanding angle of aspect can be controlled by selecting proper com-bined form and ensuring accurary of process.So laser radar tracking is realized in long distance,wide aspect angle under the bad environment. Some influences on the mea-surement are also discussed.
