Study Notes
Signals Intelligence Platforms
- Signals intelligence (SIGINT) gathers information via signal interception
- Can involve communications intelligence (COMINT), electronic intelligence (ELINT), or a mix
- Often includes cryptanalysis (analyzing encrypted messages)
- Traffic analysis (studying who and how much is communicated) can also yield valuable info
ELINT Collection Platforms
- RC-135U aircraft (modified US Air Force aircraft): primary ELINT data collection platform
- Recon, surveillance, and analysis of foreign electronic signals
- Operating since 1964, with advanced configurations
- GUARDRAIL aircraft (US Army): another long-term platform
- Locates enemy fire control radars; provides OpELINT (operational ELINT)
- Supports battlefield communication with Army and Air Force units
- Operations since the Vietnam War, continuing through Desert Storm (1991)
Technological Advancements
- Cold War advancements in ELINT: more reliable configurations and lower power consumption
- Improved equipment (e.g., radar receivers): followed advances in foreign technology
- QRC-259 receiver: developed in the 1970s for ground and airborne use; deployed until the 1990s
