Air + Radio-Wave/Air + Surveillance

Aerostat radar is a low-level surveillance system that uses aerostats (moored balloons) as radar platforms.

Aerostat radar is a low-level surveillance system that uses aerostats (moored balloons) as radar platforms.

The modern uses of radar are highly diverse, including air traffic control, radar astronomy, air-defense systems, antimissile systems; marine radars to locate landmarks and other ships; aircraft anticollision systems; ocean surveillance systems, outer space surveillance and rendezvous systems; meteorological precipitation monitoring; altimetry and flight control systems; guided missile target locating systems; and ground-penetrating radar for geological observations. High tech radar systems are associated with digital signal processing and are capable of extracting objects from very high noise levels.

The MSTAR is the Man-portable Surveillance and Target Acquisition Radar. It is an all-weather battlefield Doppler radar that operates in the J band.
