Embodiment Construction

[0029] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0030] Step 1: Determine the constraint conditions of the irradiation route as follows: the UAV flies in the form of a circular circle in front of the target, the center of the circle is selected above the connection line between the helicopter and the target, and the shortest distance between the target and the UAV is D min =2000m, UAV circling radius adopts the minimum turning radius R s =1000m, the height of the UAV remains fixed at H=2000m (relative to the height of the ground). A schematic diagram of the relative relationship among the target, helicopter, and irradiation route is attached figure 1 shown. The trapezoidal area in the figure is the helicopter attack area.

[0031] Step 2: Obtain the longitude and latitude coordinates of the target in real time from the telemetry data downloaded by the UAV (L t , B t ), helicopter longitude and latitude coo...

Abstract

The invention relates to an automatic planning method for a target irradiation course of a UAV. The method comprises that positions of a target and a helicopter are obtained, the radius of a spiral circle and the shortest distance from the target to the spiral circle are given, a direction angle is calculated, the distance between the target and the circular center is calculated, the circular center position is calculated, the circular center latitude and longitude, the direction angle and the given spiral height are sent to an airborne unit, the incidence angle and attack angle are calculated, and whether the course is changed is determined according magnitude of the incidence angle and the attack angle. The target irradiation course is generated in real time according to the helicopter attack position and target position, the UAV is guided dynamically to fly in the planed course, and the UAV can satisfy the irradiation condition when flying in the irradiation course.

Description

technical field [0001] The invention relates to the field of cooperative operations between unmanned aerial vehicles and helicopters, and more specifically refers to an automatic planning method for an unmanned aerial vehicle target irradiation route. Background technique [0002] With the development of UAV-related technologies, its battlefield advantages have become increasingly prominent in modern warfare. Compared with manned helicopters, UAVs have inherent advantages in performing long-term surveillance of specific areas, high-precision tracking of specific routes, and repetitive execution of specific tasks, and can avoid casualties. Some tasks previously completed by manned helicopters can be performed by UAVs. Using UAVs to cooperate with manned helicopters to complement the advantages of UAVs and manned helicopters is a new development trend of modern warfare. [0003] When a helicopter launches a laser-guided missile to attack a ground target, it needs a laser irra...
