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.

Target search with a radar on an airborne platform
2023 26th International Conference on Information Fusion (FUSION), 2023This paper addresses the problem of a moving target search with a discrete allocation of search effort to disjoint cones of observation. A cone covers several regions with different visibilities. This is an important step towards the optimal search with radars on airborne platforms which has not been previously studied.

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 ...

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 ...

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.

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
