The half-power point is the angle off boresight at which the antenna gain first falls to half power (approximately −3 dB) [a] from the peak. The angle between the −3 dB points is known as the half-power beam width (or simply beam width). [4] Beamwidth is usually but not always expressed in degrees and for the horizontal plane.
The Williams FW15C is a Formula One car designed by Adrian Newey and built by Williams Grand Prix Engineering for use in the 1993 Formula One World Championship.. As the car that won both the Drivers' and Constructors' Championships in the last season before the FIA banned electronic driver aids, the FW15C (along with its racing predecessor FW14B) was, in 2005, considered to be one of the most ...
The Williams FW37 is a Formula One racing car designed by Williams Grand Prix Engineering which Williams Martini Racing used to compete in the 2015 Formula One season. It was driven by Valtteri Bottas and Felipe Massa. It proved to be competitive, with both drivers scoring 4 podiums, and finishing the 2015 season in 3rd.
The Mercedes-Benz W196 (sometimes written as the Mercedes-Benz W 196 R [1]) was a Formula One racing car produced by Mercedes-Benz for the 1954 and 1955 F1 seasons. Successor to the W194, in the hands of Juan Manuel Fangio and Stirling Moss it won 9 of 12 races entered and captured the only two world championships in which it competed.
The Williams FW41 is a Formula One racing car designed by Paddy Lowe and Dirk de Beer for the Williams team, to compete in the 2018 FIA Formula One World Championship. [2] The car made its competitive debut at the Australian Grand Prix, and was driven by Lance Stroll in his second season with the team; [6] and Sergey Sirotkin, making his competitive debut in Formula One.

The Eagle Mk1, commonly referred to as the Eagle T1G, was a Formula One racing car, designed by Len Terry for Dan Gurney's Anglo American Racers team. The Eagle, introduced for the start of the 1966 Formula One season, is often regarded as being one of the most beautiful Grand Prix cars ever raced at the top levels of international motorsport. [1]
The half-power beamwidth of the main beam is 2 × Ψ 0. Preferably, when using amplitude comparison methods for direction finding, the main lobe should approximate to a Gaussian characteristic. Although the figure also shows the presence of sidelobes, these are not a major concern when antennas are used in a DF array.
The chirp pulse compression process transforms a long duration frequency-coded pulse into a narrow pulse of greatly increased amplitude. It is a technique used in radar and sonar systems because it is a method whereby a narrow pulse with high peak power can be derived from a long duration pulse with low peak power.
