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.

The Searchwater family of airborne radars
Radar Systems (RADAR 97), 1997The three radar members of the new Searchwater 2000 family are the latest in a long line of airborne radars produced in the UK since World War 2. This paper briefly outlines the development history of this family of radars and describes some of the features of the latest systems including signal processing aspects.

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.

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 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 as a Navigational Aid
Transactions of the IRE Professional Group on Aeronautical and Navigational Electronics, 1954This paper evaluates airborne radar as a navigational aid by comparing its accuracy with that of three other basic types of navigational systems. Advantages and disadvantages of its present use are discussed, and its probable future role is estimated.

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

Software development for airborne radar
IEEE International Conference on Radar, 2002Some aspects for development of software in a modern multimode airborne nose radar are described. First, an overview of where software is used in the radar units is presented. The development phases-system design, functional design, detailed design, function verification, and system verification-are then used as the starting point for the discussion ...
