Near space high-speed target plasma electromagnetic measurement system

Abstract

The invention discloses a near space high-speed target plasma electromagnetic measurement system which comprises a cylindrical horizontal vacuum cavity, wherein a nozzle plane of plasma entering the vacuum cavity cannot be coplanar with the end face of the vacuum cavity; transmitting and receiving antennas of a transmission measurement system are respectively erected on the lower guide rails on the two sides, the transmitting and receiving antennas of the transmission measurement system are symmetrically erected and can perform two-dimensional movement along the axis direction and the radial direction of the plasma, a to-be-measured target of a scattering measurement system is erected on the lower guide rail in the middle, and transmitting and receiving antennas of the scattering measurement system are all erected on the upper guide rail; and a transmitting antenna of an internal electromagnetic field measurement system is erected on any group of lower guide rails on the two side edges, and an electric field / magnetic field probe for receiving an electromagnetic field is erected on the lower guide rail in the middle. According to the invention, three measurement systems, namely, the transmission measurement system, the scattering measurement system and the internal electromagnetic field measurement system, in plasma electromagnetic measurement are considered at the same time, so that an electromagnetic scattering experiment and a transmission experiment can be configured at the same time and do not influence each other.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic measurement, and relates to a plasma electromagnetic measurement system for a high-speed target near space. Background technique [0002] Near space is the space area 20-100 km from the ground, between satellites and aviation flight areas, not only the necessary place for spacecraft to go to and from outer space, but also the flight corridor for hypersonic vehicles. As an important carrier for the development and utilization of near space, high-speed aircraft in near space will open up new areas of human activities. Historical experience shows that whichever country first masters the ability to enter and open up new areas of activity will occupy a huge strategic advantage and even absolute dominance in international competition. The characteristics of high speed, low altitude, long endurance, and reusability of high-speed aircraft in near space make it an important transportation carrier ...
