Operating principle of laser beam-riding guidance was set forth. Based on the principle of spatial frequency-encoding  experimental results demonstrated that the receiver can receive correctly the encoded signal and can decode the signal  an optimum laser encoding mode was designed  measurement for the missdistance is feasible and all the performance parameters satisfy the demand. (2012) Trans Tech Publications  which can transfer continuous laser into pulse laser that represents different position information. Then the mathematic model of deviation from target is built  Switzerland.  a modified encoding pattern was presented  which is composed of two light paths crossed 90. Azimuth information of target is given in orthogonal coordinate system and deviation from target is linearity. As well as  characteristic distribution of spatial laser field is analyzed. Corresponding decoding mode was presented  by testing in 2 kilometers outdoor
