SIGINT Techniques#
The tradecraft applied to SIGINT sources with the operator’s kit. Each technique is a repeatable procedure that turns raw data into intelligence.
Technique |
Description |
|---|---|
Spectrum sweep |
Survey a band, log peaks, identify carriers. |
Direction finding |
Bearings from multiple sensors; multilateration. |
Demodulation |
FM, AM, SSB, PSK, FSK, QAM, OFDM. |
Traffic analysis |
Metadata; talk-times, bursts, call durations, association patterns. |
Decryption |
Known weaknesses (A5/1, WEP, default keys); always within authority. |
Protocol RE |
Reverse unknown protocols with URH and gnuradio flowgraphs. |
