    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 ...

  5. Central acquisition radar (3D-CAR) - Wikipedia

    en.wikipedia.org/wiki/Central_Acquisition_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 ...

    However, the design concept surpassed the technological capabilities of the time, leading to the cancellation of the program in May 1962. The Initial Defense Communications Satellite Program (IDCSP) was proposed as one of two recommended follow-up approaches to deliver a working satellite. Philco (now Ford Aerospace) was contracted for the work.

  7. Space-based radar - Wikipedia

    en.wikipedia.org/wiki/Space-based_radar

    Space-based radar or spaceborne radar is a radar operating in outer space; orbiting radar is a radar in orbit and Earth orbiting radar is a radar in geocentric orbit. A number of Earth-observing satellites , such as RADARSAT , have employed synthetic aperture radar (SAR) to obtain terrain and land-cover information about the Earth .

  8. Man-portable radar - Wikipedia

    en.wikipedia.org/wiki/Man-portable_radar

    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.

  9. Ground-penetrating radar - Wikipedia

    en.wikipedia.org/wiki/Ground-penetrating_radar

    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.
