All you need to know about signal analysis methods
Frequency spectrum is limited but applications in mobile, wireless and satellite communications are becoming ever more diverse. Monitoring and intercepting signals across wide frequency ranges in different signal scenarios is very challenging. Comprehensive signal analysis of unknown and complex emissions also demands - great - effort. With thousands of signals occupying the frequency spectrum, the mission is to monitor all target signals, detect signals of interest and identify unknowns.
Efficient and advanced signal monitoring solutions enable surveillance of spectrum segments to detect emissions of interest which are then identified, classified and further processed (recorded, demodulated, decoded and analyzed).
- Signal surveillance: Observing (targeted monitoring) the occurrence and behavior of specific signals for situational awareness in specific signal scenarios. Surveillance systems must be able to measure unknown or “unfriendly” transmissions and extract information.
- Signal interception: Searching for, detecting, recording and reporting all signals of interest in a given scenario, often including content extraction with demodulators and decoders.
- Signal analysis: Determining technical signal parameters with automatic or manual measurements of live or recorded signals. This might also include using demodulators and decoders to resolve content from unknown signals.
