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.
