Problems solved by technology

When the missile is launched, if the photoelectric load faces the tail smoke, the tail smoke will fill the field of view of the photoelectric load, making it difficult for the photoelectric load to track and lock the target, and the laser energy will drop sharply. In severe cases, the photoelectric load will lose the target and eventually lead to attack failure

Embodiment 1

[0081] Step 1. When the UAV is flying at a predetermined altitude, according to the flight parameters of the UAV, including the flight height H, heading angle ψ, and track angle , flight ground speed|V G | and indicated airspeed |V A＇ |, the calculated wind speed in the flying airspace of the UAV is 4m / s and the wind direction is 130°. Clock hand rotation; and determining the azimuth S of the sun's illumination according to local time W is 60°, and the azimuth angle of sunlight is the angle of the incident direction of the sun's rays, taking the true north as 0°, the range is 0° to 360°, and it rotates clockwise.

Abstract

The invention relates to an unmanned aerial vehicle-based guided missile attack route planning method which comprises the following steps: calculating to obtain the wind speed and the wind direction according to fight parameters of an unmanned aerial vehicle, and determining the sun illumination azimuth angle according to local time; calculating track angles of the unmanned aerial vehicle attacked by guided missiles from the left side and the right side according to the wind speed and the wind direction, and selecting the side having the relatively small absolute value of the difference value between the track angle of the unmanned aerial vehicle and the sun illumination azimuth angle to be used as the side suitable for being attacked by the guided missiles; determining the launching off-axis angles and launching axial distances of the guided missiles according to launching requirements and trajectories of the guided missiles so as to obtain the laterodeviation of the unmanned aerial vehicle; and calculating to obtain the coordinate of laterodeviation point stroke according to the track angle, at the side suitable to be attacked by the guided missiles, of the unmanned aerial vehicle, the laterodeviation of the unmanned aerial vehicle, and known impact point coordinates and further to obtain the attack route of the guided missiles, so that the unmanned aerial vehicle flies for attacking according to the attack route. According to the unmanned aerial vehicle-based guided missile attack route planning method, use requirements of all-weather attack of the unmanned aerial vehicle are met, and the automation degree, the rapidity and the real-time performance of the attack can be improved to the greatest extent.

Description

technical field [0001] The invention relates to a missile attack route planning method. More specifically, the present invention relates to a UAV-based missile attack route planning method. Background technique [0002] At this stage, most of the airborne weapons of UAVs at home and abroad are short-range laser-guided weapons. Laser-guided weapons include laser-guided missiles and laser-guided bombs. There are two ways of laser indication: ground irradiation and same-machine irradiation. The same-machine irradiation is the main application method. It is flexible to use and can completely avoid the casualties caused by the protruding personnel in the ground irradiation method. [0003] When the UAV airborne missile is launched, the combustion of the missile engine grain will produce a large amount of tail smoke. The tail smoke is columnar in shape and expands with time. The installation position of the airborne photoelectric load and the installation position of the missi...
