Full-band electromagnetic spectrum monitoring system based on ultra-wideband antenna

Abstract

The invention discloses a full-band electromagnetic spectrum monitoring system of an ultra-wideband antenna. The full-band electromagnetic spectrum monitoring system comprises an antenna feed system,antenna switch matrix equipment, an electromagnetic environment monitoring receiver, a network switch and an electromagnetic spectrum management terminal. The antenna feed system is connected with theantenna switch matrix device and transmits received electromagnetic environment signals to the antenna switch matrix device. The antenna switch matrix device gates the corresponding monitoring antenna and transmits an electromagnetic environment signal to the electromagnetic environment monitoring receiver. The electromagnetic environment monitoring receiver arranges and analyzes the electromagnetic environment signals in real time. The antenna feed system, the antenna switch matrix device, the electromagnetic environment monitoring receiver and the electromagnetic spectrum management terminal are in communication connection with the network switch through an LAN. The antenna feed system comprises a monitoring antenna of 1.6 MHz to 30 MHz, a monitoring antenna of 30 MHz to 512 MHz, and acomposite antenna of 512 MHz to 60 GHz. The 1.6 MHz-30 MHz monitoring antenna, the 30 MHz-512 MHz monitoring antenna and the 512 MHz-60 GHz composite antenna are connected with the antenna switch matrix device through a radio frequency coaxial feeder line. According to the invention, full-band monitoring can be realized.
