The invention provides a 
laser-beam riding guidance measuring angle 
receiver and belongs to the technical field of short range surface-to-air and surface-to-surface 
missile posture measuring and controlling. The 
receiver comprises a wide-angle optical lens 
assembly, a four-quadrant photoelectric 
detector, a 
signal conversion and amplification circuit, a filter circuit and an analog-digital hybridresolving circuit. According to the 
receiver, the receiver receives modulation 
laser guidance information emitted by a ground 
laser-beam riding guidance instrument, through optical convergence imagingand real-time treatment of the 
signal conversion and amplification circuit, the shaping filter circuit and a sum-difference treatment circuit on signals, two-dimensional position coordinates of a 
missile relative to the center of an 
information field in the space laser-beam riding guidance 
information field and the 
pitch deviation angle and 
yaw deviation angle of the axis of the 
missile relativeto laser rays of the laser-beam riding guidance 
information field are obtained through a 
digital signal resolving circuit and 
software. According to the receiver, the mode of encoding laser 
direct radiation and measuring angle receiver receiving is adopted, meanwhile, the position information and posture information of the missile relative to the guidance information field are measured, accordingly, accurate position and posture angle measuring is provided for the missile, and the missile transient 
control quality is greatly improved.
