Laser-beam riding guidance measuring angle receiver

Abstract

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.

Problems solved by technology

The existing laser beam steering guidance system can only measure the position coordinates of the missile relative to the center of the laser information field, which is used in the missile guidance circuit to control the position of the missile center of mass. During the flight in the center of the field, the attitude angle of the missile body will change during this process. When the attitude angle changes beyond a certain range, such as conical pendulum movement, it will have a great impact on the accuracy of the missile, the power of the warhead, and the performance of the seeker. , so modern missile designs have increasingly adopted attitude control to improve the dynamic characteristics of the missile body in order to improve the control quality of the missile

The adoption of the attitude control loop needs to measure the attitude movement information of the missile. Traditionally, this information is measured by inertial devices such as gyroscopes. However, adding inertial devices is not only costly, but also takes up space on the missile, which will bring new problems to the overall design of the missile. come difficult
