Detection method and system of high-speed near-space aerocraft

Abstract

The invention provides a detection method and system for a high-speed near-space aerocraft. A signal produced in a physical process in a plasma sheath produced by the aerocraft self is used for detecting the aerocraft, and the method comprises the following steps: acquiring electromagnetic wave of plasma radiation for the high-speed near-space aerocraft; acquiring flight characteristics of the high-speed near-space aerocraft according to the electromagnetic characteristics carried by the electromagnetic wave of the plasma radiation, wherein the electromagnetic characteristics comprise one or combination of the frequency, delay and doppler information, and the flight characteristics comprise one or combination of the distance, the azimuth angle, the altitude angle and the speed. By applyingthe technical scheme disclosed by the invention, the effective detection of the near-space aerocraft can be realized.

Description

Technical field

[0001] The invention relates to the technical field of radar early warning, in particular to a detection method and system for a high-speed approaching space vehicle. Background technique

[0002] Adjacent space refers to the airspace with a height of 20-100 kilometers from the ground. At present, the world's major aerospace powers, dominated by the United States, have set off an upsurge in adjacent space development in order to gain an advantage and an active position in future military confrontations. The United States, Russia, Britain, Germany, Israel and other countries have all formulated their own near-space development plans, and have invested heavily in the development of near-space vehicles. Near-space aircraft refers to an aircraft that flies in adjacent space and completes related tasks. Near-space vehicles have advantages over ordinary aviation and aerospace vehicles, especially in the areas of communication support, intelligence collection, electroni...
