A vehicle-mounted radio monitoring and direction-finding system

Abstract

The invention discloses a vehicle-mounted radio monitoring and direction-finding system, which includes a short-wave monitoring antenna, an ultrashort-wave monitoring and direction-finding antenna, a microwave monitoring and direction-finding antenna, a short-wave monitoring receiver, an ultrashort-wave monitoring and direction-finding receiver, and a microwave monitoring and direction-finding receiver , network switch and operation terminal, the radio frequency output of the shortwave monitoring antenna, the ultrashort wave monitoring direction finding antenna and the microwave monitoring direction finding antenna are respectively connected with the radio frequency input of the short wave monitoring receiver, the ultrashort wave monitoring direction finding receiver and the microwave monitoring direction finding receiver, The control output and correction output of the ultrashort wave monitoring direction-finding receiver are respectively connected to the control input and correction input of the ultrashort wave monitoring direction-finding antenna, and the short-wave monitoring receiver, ultrashort wave monitoring direction-finding receiver and microwave monitoring direction-finding receiver are respectively connected to the The operator terminal is connected for data exchange. The invention can realize the monitoring and direction finding of the 2M-40GHz frequency band signal.

Description

technical field [0001] The invention relates to the field of radio monitoring, in particular to a vehicle-mounted radio monitoring and direction finding system. Background technique [0002] Radio monitoring refers to the activities of detecting, searching, and intercepting radio signals in the radio management area, and analyzing, identifying, monitoring and obtaining technical information such as technical parameters, working characteristics and radiation positions of the radio signals. It is an effective implementation It is an important basis for radio management and also an important branch of radio spectrum management. At present, most radio monitoring equipment is fixed, and the fixed structure needs to build an iron tower higher than most buildings when it is used, which has the disadvantages of high cost and limited monitoring range. At the same time, the monitoring frequency band of the general radio monitoring equipment is relatively small, and multiple radio mon...

Problems solved by technology

At present, most radio monitoring equipment is fixed, and the fixed structure needs to build an iron tower higher than most buildings when it is used, which has the disadvantages of high cost and limited monitoring range.

At the same time, the monitoring frequency band of general radio monitoring equipment is small, and multiple radio monitoring and direction-finding equipment are required to monitor the radio signal of the wide frequency band.
