Another DSP satellite was lost in 1999, DSP-19, after its Inertial Upper Stage failed following launch from a Titan 4B booster. [8] DSP-19 was a USAF Defense Support Program missile early warning satellite equipped with an infrared telescope to detect rocket launches. The Titan 4B rocket placed the IUS upper stages and payload into a 188 km x ...
STSS was designed to be the low Earth orbiter (LEO) within the layered Ballistic Missile Defense System. It complemented the geosynchronous Defense Support Program, the Space-Based Infrared System, and other overhead non-imaging infrared (ONIR) systems [15] [16] and provided tracking cues to systems on the surface. The STSS program was ...
Observation of a Delta II rocket launch by a SBIRS satellite in 2008. The United States was the first country to attempt to establish a space-based early warning system. The goal was to detect Soviet ballistic missile launches and give 20 to 33 minutes notice of the missile's arrival (against 10 to 25 minutes for the BMEWS ground-based radar ...
The central acquisition radar (CAR) is a long-range high-resolution 3D surveillance radar. [2] The entral acquisition radar was designed by Electronics and Radar Development Establishment (LRDE), a DRDO laboratory, and is produced by a joint venture between BEL, Larsen & Toubro, Astra Microwave and Entec. The radar employs a planar array ...
Illustration of the DSCS III satellite. The Defense Satellite Communications System (DSCS) [1] is a United States Space Force satellite constellation that provides the United States with military communications to support globally distributed military users. Beginning in 2007, DSCS began being replaced by the Wideband Global SATCOM system. A ...
The Blighter B202 Mk 2 radar from Blighter Surveillance Systems (a Plextek Group company) is an advanced E-Scan radar with no moving parts for high reliability in the field. Its weight is about 15 kg and is therefore truly man portable, about the weight of a machine gun and less than half the weight of other man-portable radars.
Monostatic monopulse-Doppler radar sensors offer advantages over FMCW radars, such as: Half-duplex: Pulse-Doppler radar sensors are half-duplex, while FMCW radar sensors are full-duplex. Hence, pulse-Doppler provide higher isolation between transmitter and receiver, increasing the receiver's dynamic range (DR) and the range detection considerably.
Ground-penetrating radar uses a variety of technologies to generate the radar signal: these are impulse, [48] stepped frequency, frequency-modulated continuous-wave , and noise. Systems on the market in 2009 also use Digital signal processing (DSP) to process the data during survey work rather than off-line.
