Emulational simple target simulation system for visible image guided missiles and simulation method thereof

Abstract

The invention provides an emulational simple target simulation system for visible image guided missiles. A projector is adopted to project target crosses to a projection curtain; a control computer is adopted for controlling the yawing and pitching direction angles of a triaxial turntable; a visible light guiding head is adopted for detecting the target crosses; a target display computer is adopted for target simulation; the yawing direction angle and the pitching direction angle of an externally input simulation target relative to the center of the triaxial turntable are received, the position coordinates of the cross targets in the projection image can be calculated and obtained according to a two-dimensional mapping table stored inside, and the projector is controlled to project the cross targets to the projection curtain according to the position coordinates; a calibration computer is adopted for calibration; a two-dimensional mapping table in which the yawing direction angle and the pitching direction angle of the triaxial turntable are in one-to-one correspondence with the cross targets is built and then sent to the target display computer. The system can realize simple image generation and guarantee a certain simulation precision.

Description

technical field [0001] The invention belongs to the field of semi-physical simulation technology and can be used to replace a five-axis turntable and a target simulator to complete a semi-physical simulation experiment of an image-guided weapon. Background technique [0002] Hardware-in-the-loop simulation is an indispensable and important link in the development of precision weapon systems. For missiles guided by visible light images, the current practice of hardware-in-the-loop simulation is to use a five-axis turntable to simulate the projectile body in the three axes of the five-axis turntable. Attitude, use the outer two axes to simulate the relative position of the target, and install the visible light target simulator on the outer two axes to simulate the visible light target and its background. [0003] Although the five-axis turntable solution can obtain high simulation accuracy, due to the large investment and long construction period (more than 12 months) of the f...

Problems solved by technology

[0003] Although the five-axis turntable solution can obtain high simulation accuracy, due to the large investment and long construction period (more than 12 months) of the five-axis turntable and the special target simulator, many semi-physical simulation laboratories are in the process of model development. In the early stage, the conditions for terminal guidance simulation could not be met, which delayed the development progress of the model
