New Airborne Weather Radar Systems
Journal of Aircraft, 1981This pajvev reviews the characteristics of airborne weather radars produced since World War II, citing the major technology changes that have been implemented up to the present time. The recent advent of large scale integrated (LSI) circuits has made it possible to design practical color radar displays which are more easily interpreted by the pilot ...

Retrodirective airborne radar for urban surveillance
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008Urban surveillance with airborne radar systems is very challenging due to blockage of line-of-sight caused by buildings. To overcome this limitation, it is very likely that the radar will be mounted on a small, inexpensive unmanned aerial vehicle (UAV) that can fly directly over an urban area of interest. Unfortunately, such systems provide very little

Digital signal processing in airborne radar
Digital Signal Processing, 1992My introduction to the real world of radar digital signal processing occurred in 1959. Our airborne radar design team at General Electric had contracted to design and produce an advanced airborne surveillance radar for the U.S. Navy Hawkeye aircraft (E2A).

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 ...

Passive radar is one of the most rapidly developing fields in the radar technology in recent years. The ground-based passive radar technology is now entering a stage of maturity. In the past, in a case of active radars, the technology developed for ground-based sensing was adapted for airborne platforms.

The concept of airborne passive radar
2011 MICROWAVES, RADAR AND REMOTE SENSING SYMPOSIUM, 2011This paper presents the concept of an airborne passive radar and the preliminary results of the experiments carried out using two mobile platforms: a car and an aircraft. In the research conducted for the study of this concept, a passive radar mounted to an aircraft was used.

Reconfigurable arrays for airborne radars
NTC '91 - National Telesystems Conference Proceedings, 2002The concept of reconfigurable, multiple beam antenna arrays is discussed as a likely step in the development of future airborne radar systems. The system advantages of reconfigurable multiple beams are explored in terms of airborne tactical radars and their application.

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

A Multichannel airborne radar dataset
2017 IEEE Radar Conference (RadarConf), 2017The U.S. Naval Research Laboratory (NRL) recently developed an airborne Multichannel Synthetic Aperture Radar (MSAR) test bed system consisting of 32 along-track phase centers using two transmit horns and 16 receive antennas. NRL has deployed this system to perform extensive and systematic data collections on a variety of small maritime craft under ...

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
