Embodiment Construction

[0010] Reference figure 1 , image 3 , The present invention includes an analog seeker 10 and a motion simulation platform. The analog seeker is composed of a pan / tilt 21 and a camera 22. The camera uses a digital zoom CCD camera to simulate distance changes by changing the focal length. The entire pan / tilt movement and CCD camera The adjustment of the analog seeker adopts digital control. The analog seeker adopts a camera. It is recommended to use a high-speed smart dome camera, which should have at least 22x optical zoom and 10x digital zoom, which can monitor the field of view in 360°, and can rotate at high speed and horizontally. The speed is not less than 240° / s, and the vertical is not less than 150° / s. The manual speed is not less than 0.8°-90° / s for horizontal and 0.8°-45° / s for vertical. The minimum illuminance is 0.01LUX for color and 0.003LUX for black and white. It is best to have a dynamic image detection function. The analog seeker has the advantages of long ser...

Abstract

The invention relates to a terminal guidance section simulation system, which comprises a guidance head and a movement simulation platform, wherein the guidance head adopts a simulation guidance head and consists of a holder and a camera; the movement simulation platform is of a net-type supporting frame which is provided with a guide rail installation beam and a transmission belt, wherein a precise guide rail is installed on the bottom part of the guide rail installation beam, a large installation platform is installed between two guide rail installation beams, a small installation platform is installed on the side surface of the guide rail installation beam, a roll-over drag chain is installed at the left side of a stepper motor, and the simulation guidance head is installed below the large installation platform. By adopting the simulation guidance head, the terminal guidance section simulation system has the advantages of long service life, high cost performance and simple structure; and the movement simulation platform adopts a steel tube net rack as a supporting frame, adopts the precise guide rail as the movement restriction, adopts the large-power stepper motor, the high-strength transmission belt and the roll-over drag chain as the towing, and adopts the computer to carry out the movement control, so the simulation system has the advantages that the simulated range of the earth surface for missile to pass is large, the platform motion is stable and is free from jumping, and the computer can conveniently perform the precise control.

Description

Technical field [0001] The invention relates to a simulation system for the terminal guidance stage, which meets the requirements of ground simulation, experiment and verification during the precise strike process of the terminal guidance stage of a TV-guided missile through a semi-physical simulation method. Background technique [0002] At present, the simulation research of searching, identifying and tracking the target captured by the seeker in the terminal guidance stage generally adopts the missile-borne optical TV image tracking seeker at home and abroad. Using the seeker's pitch search speed to balance the longitudinal movement speed of the line of sight caused by the flight speed of the missile, a search scheme with one-dimensional visual effect is obtained, so that the image on the monitor only moves smoothly in the horizontal direction. The disadvantage is that the focus adjustment range of the seeker optical system is small, which cannot meet the ground simulation req...
