Flexnet™ is a Unattended Ground Sensor capability, [9] from the Swedish company Bertin Exensor, subsidiary of Bertin Technologies. It includes sensors with embedded processing, GPS, and radio communication. Those sensors are based on seismic-acoustic detection, passive infrared, electro-optical and magnetic detection techniques.
ground-based Republic of China ... AN/SPS-41 Navigational radar for small boats. [53] ... AN/APN-227 Doppler radar sensor by Canadian Marconi Company for P-3C;
This is an incomplete list of ground-based radars operated by the United States Marine Corps since the service first started utilizing radars in 1940. [1] The Marine Corps' has used ground-based radars for anti-aircraft artillery fire control, long range early warning, Ground-controlled interception (GCI), ground directed bombing, counter-battery radar, short-range cueing for man-portable air ...
Ground-penetrating radar antennas are generally in contact with the ground for the strongest signal strength; however, GPR air-launched antennas can be used above the ground. Cross borehole GPR has developed within the field of hydrogeophysics to be a valuable means of assessing the presence and amount of soil water .
Its location close to the southern Former Soviet Union made it the only ground sensor capable of tracking actual deorbits of Russian space objects. In addition, the Pirinclik radar was the only 24-hour-per-day eastern hemisphere deep space sensor. Radar operations at Pirinclik were terminated in March 1997.
Surveillance radar (mostly X and S band, i.e. primary ATC Radars) Tracking radar (mostly X band, i.e. Fire Control Systems) Wearable radar and miniature radar systems are used as electric seeing aids for the visually impaired, as well as early warning collision detection and situational awareness
Millimeter wave (mmWave) sensing is a non-contact system of using mmWave radar sensors to measure movement, acceleration, and angles as small as a fraction of a millimeter. [1] This system requires a mmWave radar sensor to transmit and receive pulses of millimeter electromagnetic wave energy, detecting targets and motion from the reflections it ...
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
