- Intelligence collection management : Assigning questions to various collection techniques, reflecting the techniques available and the priority of the information need. Includes the process of categorizing information learned for subsequent analysis, and assigning probabilities of accuracy to the raw information
- Radar : (acronym for "radio detection and ranging") A technique used for detecting and tracking targets, navigation, imagery, and special applications.
- Radio : Transmission and reception of information, which can be voice, data or imagery over electromagnetic radiation in free space (i.e., wireless). The information is modulated onto a carrier wave
