Warning method and device for invasion of aerial target in restricted airspace

Abstract

The invention discloses a warning method and device for the invasion of an aerial target in a restricted airspace. The warning method comprises the following steps of: determining an extrapolated warning track point of the aerial target; judging whether the extrapolated warning track point is located in a regular body, wherein the regular body is predetermined to include the restricted airspace; confirming not to give an alarm if the extrapolated warning track point is located out of the regular body; or further judging whether the extrapolated warning track point is located in the restricted airspace; and confirming to give the alarm if the extrapolated warning track point is located in the restricted airspace. According to the invention, the step of judging whether the extrapolated warning track point is located in the regular body which includes the restricted airspace is carried out before the step of judging whether the extrapolated warning track point is located in the restricted airspace, and the step of judging whether the extrapolated warning track point is located in the regular body is characterized in very simple calculation process and small calculating amount, so that alarm judging time is shortened, and therefore time is saved for judging the next alarm cycle, and warning timeliness is improved.

Description

technical field [0001] The invention relates to the general aviation communication technology, in particular to the warning technology when the air target invades the restricted airspace. Background technique [0002] In recent years, general aviation has developed rapidly. Business flight, commercial flight, air tour, and private driver's license training are being favored by more and more people, and there is a large enough market demand. Statistics show that there are currently about 336,000 general-purpose aircraft in the world, and 700,000 pilots engaged in general aviation activities. Therefore, general purpose aircraft plays a very important role in the economy of the country. [0003] The rapid development of general aviation has also brought great potential safety hazards in the air. Aircraft in general aviation are different from airplanes in civil aviation. Their flight routes and altitudes are not fixed, and they change at any time during the flight. A specif...

Problems solved by technology

[0012] To sum up, the air traffic control system of the prior art carries out the method of intrusion warning (or early warning) to air target, and the operation time is long, causes warning (or early warning) response to be slow, under the situation that air target accelerates suddenly, may A situation that cannot be warned (or early warning) in time
