-
A.
USAF global HF direction-finding network
The USAF global HF direction-finding network was a worldwide system of high-frequency radio interception and triangulation sites used by the U.S. Air Force for signals intelligence and locating radio transmissions during the Cold War.
-
B.
Dual Frequency Synthetic Aperture Radar
Dual Frequency Synthetic Aperture Radar is a lunar-mapping radar instrument that uses two microwave frequency bands to image the Moon’s surface and subsurface, particularly to detect and characterize water ice and regolith properties.
-
C.
Bistatic Radar
Bistatic radar is a radar system in which the transmitter and receiver are located at separate sites, enabling specialized measurements such as detailed surface and composition analysis of planetary bodies.
-
D.
FLR-9 antenna array
chosen
The FLR-9 antenna array is a large, circular high-frequency direction-finding system used during the Cold War for long-range signals intelligence and communications interception.
-
E.
passive electronically scanned array
A passive electronically scanned array is a type of radar antenna system that steers its beam electronically using multiple fixed radiating elements fed by phase shifters, rather than by mechanically moving the antenna.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
