Problems solved by technology

Since the high temperature generated by the strong friction between the projectile and the atmosphere can reach hundreds of degrees Celsius, it is difficult for ordinary antennas to work normally or even be completely damaged at such high temperatures. This requires the design of a special structure antenna that can reliably and stably Work

Abstract

The invention discloses a high temperature resistant antenna, which comprises a radome, an antenna main body and a heat insulating material layer; the radome is made of a high temperature protection material and defines an accommodating space; the antenna main body is arranged in the accommodating The accommodating space, the heat insulating material layer is arranged in the accommodating space and wraps the antenna main body. The invention adopts thermal protection and thermal isolation double-layer technology, can work stably and reliably in a high temperature environment up to hundreds of degrees Celsius, meets the requirements of electrical performance indicators and mechanical performance indicators; and its radome can conform to high-speed aircraft by adopting The structural design meets the aerodynamic performance requirements of high-speed aircraft.

Description

technical field [0001] The invention relates to an antenna, in particular to a high temperature resistant antenna. Background technique [0002] With the rapid development of satellite navigation technology, its application fields have been continuously expanded to include surveying and mapping, telecommunications, transportation, water conservancy, marine fishery and geological exploration and many other fields, and it plays a huge role in national defense and modern warfare. Target positioning and precision guided missiles generally use satellite navigation systems. In addition to meeting the electrical performance, the missile-borne satellite navigation antenna must also meet the special requirements of the missile-borne environmental performance. These special requirements include traveling with the missile body to meet the aerodynamics of the missile body Performance requirements, high-intensity vibration and high-temperature performance requirements. Since the high te...
