Charvat is best known for his through-wall radar imaging system [1] [2] and his project-based MIT short-course on radar, where each student builds their own radar system. [3] [4] This radar course has been adopted by numerous other universities and institutions. Charvat is also well known in the hacker and maker community for developing radar ...
Reflective array 'billboard' antenna of the SCR-270 radar, an early US Army radar system. It consists of 32 horizontal half wave dipoles mounted in front of a 17 m (55 ft) high screen reflector. With an operating frequency of 106 MHz and a wavelength of 3 m (10 ft) this large antenna was required to generate a sufficiently narrow beamwidth to ...
The RR-144 is designed to prevent interference with civil ATC radar systems. Chaff, originally called Window [1] or Düppel, is a radar countermeasure involving the dispersal of thin strips of aluminium, metallized glass fiber, or plastic. [2] Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. [3]
The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased-array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

The second system would have been located in the south and together the PAVE PAWS sets would have provided Taiwan with 360-degree coverage. [59] The radar site in Taiwan sits on top of a mountain at an elevation of over 2,600 m (8,500 ft). [60] Due to its extremely elevated position the Taiwanese set has the unique ability to track surface ships.
Perimeter surveillance radar (PSR) is a class of radar sensors that monitor activity surrounding or on critical infrastructure areas such as airports, [1] seaports, military installations, national borders, refineries and other critical industry and the like. Such radars are characterized by their ability to detect movement at ground level of ...

The cavity magnetron is a high-power vacuum tube used in early radar systems and subsequently in microwave ovens and in linear particle accelerators. A cavity magnetron generates microwaves using the interaction of a stream of electrons with a magnetic field , while moving past a series of cavity resonators , which are small, open cavities in a ...
