The ground radar station submits a transmit command and takes a measurement of the satellite's location. The transponder's signal is received by a radar receiver and combined with the satellite's ephemeris data to calculate the satellite's actual position, and this is then compared with the position calculated by the radar measurement in order ...
Video detection and ranging (VIDAR) is a technique to measure the speed or other information of a distant vehicle using advanced stereoscopic imaging techniques. VIDAR technology has application in remote sensing , traffic enforcement .
TPY-2 radar in travelling configuration View from the back on a deployed TPY-2 radar. The AN/TPY-2 Surveillance Transportable Radar, also called the Forward Based X-Band Transportable (FBX-T) is a long-range, very high-altitude active digital antenna array [1] [2] X band surveillance radar designed to add a tier to existing missile and air defence systems.
This worked by capturing the entire "video" signal being sent to a cathode ray tube display, using it to frequency modulate a microwave signal, and then sending the resulting signal to L1 using wideband microwave relays. Operators at L1 would then see the radar signals as they were at the stations, and use them to extract "tracks" of interest.
Some are deployed on a basis of one radar supporting a battery of six gun mountings. In 2005 the Netherlands Ministry of Defence (MoD) announced the delivery of eight Flycatcher search and tracking radar fire-control systems for low-level air defense with 16 Bofors Defense 40 mm L/70 guns to Thailand through Thales .
The EL/M-2248 MF-STAR is a GaN based multifunction active electronically scanned array naval radar system developed by IAI Elta for maritime installation on warships. [3] It is capable of tracking both air and surface targets and providing fire control guidance. MF-STAR is an acronym of Multi-Function Surveillance, Track And Guidance Radar. [4]
Luigi Mangione, the man accused of fatally shooting UnitedHealthcare CEO Brian Thompson earlier this month, is facing upgraded murder charges in New York, officials announced on Tuesday. Mangione ...
The F-22 radar from Lot 5 aircraft onward is the APG-77(V)1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities. [5] In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1–11 test aircraft. The radar system had accumulated over 300 flight hours by 2010.
