Embodiment Construction
[0035] The content of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0036] This embodiment provides an angle-measuring receiver based on the laser beam steering guidance system, which can obtain the two-dimensional position coordinates ΔY, ΔZ of the laser beam steering guided missile relative to the center of the guidance laser information field in the space laser beam steering guidance information field And the pitch offset angle and yaw offset angle of the missile axis relative to the laser beam of the laser beam steering guidance information field (that is, the central axis of the laser).
[0037] The receiver is placed at the tail of the missile body, and its measurement principle is as follows: figure 1 As shown, after take-off, the missile flies in the laser guidance information field (the area surrounded by the edge of the coding guidance laser field, and the axial section of the guidance laser inf...

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.
Description
technical field [0001] The invention relates to a receiver, in particular to an angle-measuring receiver for laser beam steering guidance, and belongs to the technical field of ground-ground and ground-air short-range missile control and attitude measurement. Background technique [0002] Ammunition, as the terminal of the weapon system, directly determines the effectiveness of the strike and the outcome of the battlefield. With the changes in the combat mode and combat method of modern warfare, major military powers are vigorously developing information-based intelligent ammunition weapon systems characterized by high first-shot hit rate, no matter after launch, and high-efficiency damage. Laser-beam-guided munitions have become an important development field and direction of intelligent munitions due to their advantages such as high guidance precision, low cost, small collateral damage, fast response time, and high combat effectiveness.
