An electromagnetic environment effect test method and system capable of simulating the air flight state of an unmanned aircraft

Abstract

The invention discloses an electromagnetic environment effect test method and a system for simulating a flight state of an unmanned aerial vehicle. The method comprises the following steps: firstly, an ultrawideband electromagnetic pulse generator is used as a radiation source, and a test bed placed with the unmanned aerial vehicle is arranged rightly in front of the ultrawideband electromagnetic pulse generator; a ground control platform is put on the side surface of the ultrawideband electromagnetic pulse generator, and is connected with a radiation antenna through an adjustable attenuator; electronic equipment in the unmanned aerial vehicle is normally opened; then, an attenuation quantity of the adjustable attenuator is increased, a radiation signal sent by the radiation antenna is reduced until the unmanned aerial vehicle is out of control; the ultrawideband electromagnetic pulse generator is opened to generate an electromagnetic environment to be tested; the position of the unmanned aerial vehicle is adjusted to radiate one part of the unmanned aerial vehicle; and the electromagnetic interference resistance of the unmanned aerial vehicle is observed and recorded on the ground control platform. The method has the following advantages: a real magnetic sensitive threshold of the unmanned aerial vehicle can be obtained; and the method is truly used for guiding the flight electromagnetic safety of the unmanned aerial vehicle.

Description

technical field [0001] The invention belongs to the field of electromagnetic environment effect test, and in particular relates to an electromagnetic environment effect test method and system capable of simulating the flying state of an unmanned aircraft in the air. Background technique [0002] Unmanned aircraft is an aerial vehicle controlled by a ground control platform, which can be used for air operations in complex areas. At present, there are more and more types of unmanned aircraft, and their applications are becoming more and more extensive. Due to the pursuit of lightness, unmanned aircraft generally use composite materials for their shells, which basically have no shielding ability. On the other hand, UAVs are highly electronic. When flying in the air, the ground control platform and UAVs exchange information through electromagnetic waves, and their working status is easily affected by the electromagnetic environment. [0003] At present, there is no electromagne...

Problems solved by technology

[0004] At present, there are the following problems in carrying out the electromagnetic environment effect test of unmanned aircraft under laboratory conditions: First, how to realistically simulate the change of the flying attitude of the unmanned aircraft in the air, and the unmanned aircraft has a certain inclination angle change with the horizontal line when climbing and diving The second is how to realistically simulate the dynamic change process of the flight distance of the unmanned aircraft, because the strength of the electromagnetic waves used for information interaction between the unmanned aircraft and the ground control platform is different, and the difficulty of being affected by the electromagnetic environment is also different. changing
