Turntable for semi-physical simulation of laser terminally guided projectile

Abstract

The invention relates to a laser terminally guided projectile and particularly discloses a turntable for the semi-physical simulation of the laser terminally guided projectile. The turntable comprises a table body and a control cabinet, wherein the table body is used for simulating a projectile body attitude motion characteristic or a projectile body-target relative motion characteristic, can be used for load mounting and is provided with an angle measurement element so as to supply a corner signal to serve as position feedback and speed feedback; the control cabinet is used for realizing the control over the table body; the control cabinet comprises an upper computer and a lower computer; the upper computer can interact with an operator through a human-machine interface so as to realize control instruction input, configuration data correction, safety protection, system state monitoring, and data receiving and processing for the turntable; and the lower computer can be connected with the upper computer through a high-speed serial interface and connected with the table body through a cable so as to complete the real-time control over the table body.

Description

technical field [0001] The invention relates to a laser terminal guided projectile, and in particular discloses a turntable for semi-physical simulation of a laser terminal guided projectile. Background technique [0002] Laser terminal guided shells refer to the ammunition that installs a laser seeker on the head of ordinary ammunition, guides it at the end of the flight trajectory, and performs precise strikes on the target. Laser terminal guided weapons have the advantages of high precision, strong anti-interference ability, simple structure, and low cost. Accuracy is a distinctive feature of laser guided weapons. The system implements effective jamming, so it has advantages that other guidance methods cannot match, and all military powers are also competing to develop it. In recent local wars after the Vietnam War, laser-guided weapons have shown great power, which has attracted more and more attention. Among them, the laser terminal guided projectile is an important l...

[0017] 2) Reflection type: This method is the reproduction of the actual working mode of the laser semi-active guided weapon in the laboratory, which can overcome the shortcomings of the direct irradiation method, but the implementation is more complicated

The characteristic of this scheme is that it can add complex optical background characteristics, but the cost is high, and it cannot be used in common with other optical homing guidance simulation scheme equipment. When it is used for penetrating projectiles with a large range of line of sight, the diffuse reflection plate must be far away from the turntable. Recently, the reflection spot is easily deformed, and the similarity relationship of spot size control is complicated, and the relationship between the rotation angle of the two-axis turntable and the line-of-sight angle formed by the spot on the diffuse reflection plate and the seeker cannot be accurately analyzed.
