Problems solved by technology

However, most of the existing electromagnetic pulse suppression components are directly connected in series to the cable line or built into the equipment, which is inconvenient to use and maintain, and most of them can only protect against a single electromagnetic pulse

Abstract

An electromagnetic pulse protection method for an aircraft communication and navigation system, which includes an antenna and a transceiver, and a suppressor is connected in series between the antenna and the transceiver, and the suppressor is an independent structure that encapsulates suppression components. The suppressor is provided with a mounting base and two connecting plugs, one of which is a pin plug for connecting with an antenna, and the other connecting plug is a female plug for connecting with a transceiver.

Description

technical field [0001] The invention belongs to the technical field of aviation radio, in particular to an electromagnetic pulse protection method for aircraft communication and navigation systems. Background technique [0002] At present, the electromagnetic environment in which aircraft are located is becoming more and more complex and harsh, among which lightning electromagnetic pulse and nuclear electromagnetic pulse (HEMP) are particularly prominent. Electromagnetic pulse (EMP) is a short-lived transient electromagnetic phenomenon, which is emitted through electromagnetic waves in the form of space radiation propagation. As avionics equipment and systems become increasingly multi-functional, digital, miniaturized, and integrated, the system is more vulnerable to damage by strong electromagnetic pulses. These electromagnetic pulse couplings can make the field strength at the antenna port through radiation coupling to the airborne antenna. As a result, it will interfere ...
