Vehicle-mounted radio monitoring direction-finding system

Abstract

The invention discloses a vehicle-mounted radio monitoring direction-finding system. The vehicle-mounted radio monitoring direction-finding system comprises a short-wave monitoring antenna, an ultrashort-wave monitoring direction-finding antenna, a microwave monitoring direction-finding antenna, a short-wave monitoring receiver, an ultrashort-wave monitoring direction-finding receiver, a microwave monitoring direction-finding receiver, a network interchanger and an operating terminal, wherein the radio frequency output end of the short-wave monitoring antenna, the radio frequency output end of the ultrashort-wave monitoring direction-finding antenna and the radio frequency output end of the microwave monitoring direction-finding antenna are connected with the radio frequency input end of the short-wave monitoring receiver, the radio frequency input end of the ultrashort-wave monitoring direction-finding receiver and the radio frequency input end of the microwave monitoring direction-finding receiver, the control output end and the correction output end of the ultrashort-wave monitoring direction-finding receiver are connected with the control input end and the correction input end of the ultrashort-wave monitoring direction-finding antenna, and the short-wave monitoring receiver, the ultrashort-wave monitoring direction-finding receiver and the microwave monitoring direction-finding receiver are connected with the operating terminal through the network interchanger so that data exchange can be conducted. By the adoption of the vehicle-mounted radio monitoring direction-finding system, monitoring direction-finding of signals in the frequency band ranging from 2 M to 40 GHz can be achieved.

Description

Technical field [0001] The invention relates to the field of radio monitoring, in particular to a vehicle-mounted radio monitoring 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 An important means basis for radio management is also an important branch of radio spectrum management. At present, most radio monitoring equipment is fixed, and the fixed structure needs to be built higher than most buildings when in use, which has disadvantages such as expensive cost and limited monitoring range. At the same time, the monitoring frequency band of general radio monitoring equipment is relatively small, and multiple radio monitoring direction-findi...

AI Technical Summary

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.
