Proceedings of the IEEE, 1985
Airborne Early Warning (AEW) Radar meets the operational requirement of detection and tracking of both low- and high-flying aircraft. The important and fundamental radar parameters of RF, PRF, pulse length, and transmitter power are discussed together with a number of factors relating to the antenna.

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 ...

The Reliability of Airborne Radar Equipment
Journal of the Operations Research Society of America, 1953One of the current aims in the design of electronic machines is the development of higher performance equipment utilizing, where possible, automatic control, guidance, and computing features. The incorporation of these features generally results in more complex and, hence, less reliable equipment.

Developments in Airborne Entomological Radar
Journal of Atmospheric and Oceanic Technology, 1996Abstract Radar has been used to study insect flight for over 20 years. Radar, especially airborne radar, is unrivaled in its ability to observe the spatial organization of insect migration. This paper reports methods of data collection and analysis used by current airborne entomological radar systems and, in particular, the method used to review the ...

SAE Technical Paper Series, 1967
<div class="htmlview paragraph">A number of design parameters are traded off in the design of an airborne weather radar system. The inter-relative effects of design tradeoffs can be meaningfully approximated by application of the standard range equation which takes into account such items as peak transmitter power, width of the transmitted pulse,

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).

Proceedings of the IRE, 1946
The extension of radar to airborne applications is a natural evolution of its surface development. Aircraft radar fills a most important gap. in aeronautics-that of providing actual contact with the earth's surface under all conditions of altitude, weather, and visibility.

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
