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.

Ground-based radar systems have been used to observe clouds and precipitation since the 1940s. While weather radars that use centimeter waves can observe precipitation several hundred kilometers away, radars that are dedicated to cloud observations use millimeter waves and have limited ranges of just a few tens of kilometers.

Advanced radar modes for airborne surveillance radars
2015 16th International Radar Symposium (IRS), 2015The pod integrated variant of the airborne SmartRadar by AIRBUS Defence & Space, mounted under the wing of a Learjet 35 aircraft, is used as a testbed to develop advanced radar modes. The SmartRadar comprises a multi-phase-centre active electronically steered array (AESA) antenna, a flexible, wide-bandwidth radar core, and an on-board processing unit ...

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 ...

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 ...

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,

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.

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.

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 ...

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 ...
