IEEE International Geoscience and Remote Sensing Symposium, 2003
This paper examines two applications of a multi-channel airborne radar system, or an array-based synthetic aperture radar (SAR). The first mode involves a stripmap SAR array whose electronically-steered beam patterns are exploited to achieved the azimuth resolution of its single element while maintaining a relatively high radar power; this system has ...

Airborne fire control radars (FCRs) on fast strike aircraft are the quintessential pulse Doppler radars. They must work in a wide variety of air-to-air and air-to-ground modes, they must be lightweight and compact, yet they have to achieve long detection ranges in the presence of extreme clutter scenes and be capable of tracking a large number of agile

Airborne early warning (AEW) radars provide long-range surveillance from an airborne platform. Their primary targets of interest are hostile aircraft. Long-range radar surveillance coverage can be limited by the range to the horizon; however, satisfactory range can be re-established by placing the surveillance radars at high altitude. The line of sight

Airborne Radar Signal Processor Realisation
2017 IEEE International WIE Conference on Electrical and Computer Engineering (WIECON-ECE), 2017Signal processor for airborne Active Electronically Scanned Array (AESA) radar has stringent requirement in terms of dynamic load handling, latency and throughput requirement. In this paper, Radar Signal Processor(RSP) realisation for airborne radar is discussed with specific emphasis on S/W architecture for its deployment on multiprocessor based H/W ...

Multirole airborne radar computer evolution
2014 International Radar Conference, 2014The use of AESA antennas (Active Electronically Scanned Array) in airborne radars is a breakthrough in terms of operational capabilities, compared to classic radars working with PESA antennas (Passive Electronically Scanned Array). Multi-chanel receivers allow designers to use more complex and more sophisticated algorithms.

Airborne/Spaceborne Radar: Panel Report
1990Mobile radar platforms can provide unique observations of geophysical phenomena for scientific research and for operational applications such as reconnaissance and flight safety. The advantages of an airborne or spaceborne radar are obvious; the radars provide 1) observations where it is often impractical or too costly to place a ground-based radar (e.

Monopulse Aerials for Airborne Radars
4th European Microwave Conference, 1974, 1974The paper begins by summarising the characteristics of a number of mono-pulse aerials applicable to airborne radar. For such a use, it is often important that the aerial has low side lobes. Good sidelobe performance may be obtained with a flat plate array which can have an accurately controlled aperture distribution and is free from feeder blockage and

The main objective of this chapter is to describe how an airborne pulse-Doppler radar isolates targets of interest from clutter and measures target range and velocity. Related topics such as pulse compression, automatic detection, target tracking, and target and clutter statistics are described.

Airborne Storm Avoidance Radar Training
IRE Transactions on Aeronautical and Navigational Electronics, 1957In training scheduled air carrier flight crews in the use of airborne storm avoidance radar, a twofold problem is encountered. The utility of the instrument must be sold to the doubting Thomas who has many thousands of hours flying in thunderstorm conditions, and its limitations must be defined for those who see it as a miracle maker.

Journal of Navigation, 1962
Many airborne doppler radars in use at present work with several beams in fixed directions and a pair of beams switched in sequence. In this paper, which was presented at the convention held in Dusseldorf in May 1961 (Journal, 14, 480), a new type of doppler radar is described in which a single beam is rotated around the vertical axis with a uniform ...
