Radio Monitoring System

Radio monitoring as a system subsists as long as radio communication has become omnipresent. However, the systems evolve continuously as new frequency ranges get in reach of technical proficiencies and thus, the amount of radio communication is ever rising.

The employment of a radio monitoring system is not mere an element of homeland protection but also a technical requirement to assure that nobody is abusing spectrum and thereby generating unwanted interference for other applications.

Understanding the Radio Monitoring System & it’s significance.

Radio monitoring mainly refers to the technique of methodological listening to radio transmissions to collect intelligence. Monitoring the radio spectrum is equally imperative for civil regulatory establishments, the military, and commercial network operators. In other words, Radio Monitoring Systems are powerful computerized systems, designed for monitoring and analysing the electromagnetic environment. These types of systems are mostly designated for permanent automatic monitoring in a specific or various selected areas so that any kind of signal (threat) could be identified. Such systems often come coupled with capability to detect the direction from where the signal is being transmitted.

Most of the latest spectrum radio monitoring systems ordinarily comprises of diverse parts and subsystems that makes an integrated functional unit. Among them – receivers, antennas, direction finders and analyzing equipment coexists and as a rule, within a radio monitoring system they represent specific automated systems with functions of visualization, monitoring and analysis. They comprise several distributed, intelligent subsystems for the purpose of detection and to measure electromagnetic emissions operating in a consistent manner within the monitoring system. The software within the system manages the workflow and tasks on the entire monitoring process, the data flow and its management.

Stratign’s Radio Monitoring Solution: HF/VHF/UHF Monitoring & Direction-Finding System

The HF and VHF/UHF Radio Monitoring System is fabricated and integrated for the objective of passive monitoring, logging and evaluation of target HF/VHF/UHF radio links.

For wideband scanning of the selected spectrum, the solution has a Wideband Search and Intercept Receiver with wideband Direction Finding receivers to evaluate and oversee radio transmissions in HF/VHF/UHF bands. These can also be integrated with Multi-Channel Monitoring Receivers to inspect multiple radio communication frequencies of interest along with DF of individual narrowband signals.

The system comes with a software-oriented signal classifier and top-level protocol decoding system for decoding of information protocols used in radio transmissions.

The system can be provided in both static and transportable configurations where all the modules are effortlessly integrated to offer an all-inclusive and monitoring surveillance platform to the operator for effectual and efficient monitoring process. The system can be easily employed in any configuration of customer’s need.
