Guidance unmanned aerial vehicle net cast interception method for "low-altitude, slow-speed and small" target

Abstract

The invention relates to a guidance unmanned aerial vehicle net cast interception method for a "low-altitude, slow-speed and small" target. The guidance unmanned aerial vehicle net cast interception method comprises the steps that an unmanned aerial vehicle is set as the standby state; a ground control station determines a threat target and controls photoelectric detection equipment to perform dynamic tracking on the threat target; the ground control station acquires the location of the threat target and transmits a flight instruction to the unmanned aerial vehicle; and the unmanned aerial vehicle enters the maneuvering flight mode and reaches the area near the target. When the distance between the unmanned aerial vehicle and the target is less than a first threshold, the unmanned aerial vehicle is controlled to accurately approximate the target through a visual guidance device and a distance measurement device. When the distance between the unmanned aerial vehicle and the target is less than a second threshold, a net cast device is automatically triggered to emit an interception net to wind the target to fall off and finally the unmanned aerial vehicle returns. With application of the method, the net cast device is automatically triggered to intercept the target according to the relative location information between the unmanned aerial vehicle and the target so that the interception precision and the degree of automation can be effectively enhanced.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a method for guiding a drone to throw a net and intercept a "low, slow and small" target. Background technique [0002] "Low, slow and small" targets refer to aircraft with low flying altitude, slow flying speed, and small characteristic signals, such as aviation models (fixed wing, multi-rotor, helicopter), air balloons, power delta wings, gliders, etc., which have low cost, It has the characteristics of simple operation and convenient take-off and landing. In some important occasions such as large-scale sports games and conferences, or in the case of war, it is easy to be used by criminals or hostile forces as a tool for carrying explosives, releasing biochemical agents, and disseminating leaflets. How to effectively defend against the interference and sabotage of "low, slow and small" targets has become a worldwide problem in daily maintenance of air flight order and safety....
