Visual Simulation Method of Fresnel Lens Optical Landing Assist System Based on Spatial Position

Abstract

The invention discloses a visual simulation method for a Fresnel lens optical landing aid system based on spatial positions. The visual simulation method includes the following steps that coordinatesof the Fresnel lens optical landing aid system, coordinates of a lower slideway inlet, the layer height h of a light beam at the lower slideway inlet, and the height h<0> of the distance between the lower surface of the light beam at the lowest layer at the lower slideway inlet and the plane of an aircraft carrier deck are obtained; real-time coordinates of an aircraft are obtained; whether the aircraft enters the lower slideway inlet or not is judged so as to judge whether the optical landing aid system needs to be started or not; real-time calculating is conducted according to coordinates ofthe aircraft, coordinates of an aircraft carrier and the coordinates of the Fresnel lens optical landing aid system to judge the flight height situation of the aircraft at this moment; lamp light codes are output according to the different flight height situations of the aircraft; and lamp light is displayed from the view of a pilot according to the output codes. According to the visual simulation method, according to the basic parameters of the aircraft carrier and a landing aid device of the aircraft carrier, calculation is conducted through the spatial positions of a shipboard aircraft andthe Fresnel lens optical landing aid system, and the Fresnel lens optical landing aid system is fast and visually simulated.
