Radio-frequency (RF) engineering is a subset of electrical engineering involving the application of transmission line, waveguide, antenna, radar, and electromagnetic field principles to the design and application of devices that produce or use signals within the radio band, the frequency range of about 20 kHz up to 300 GHz. [1] [2] [3]
The change of repetition frequency allows the radar, on a pulse-to-pulse basis, to differentiate between returns from its own transmissions and returns from other radar systems with the same PRF and a similar radio frequency. Consider a radar with a constant interval between pulses; target reflections appear at a relatively constant range ...
Beam forming: The beam is formed in the digital (digital beamforming (DBF)), intermediate frequency (IF), optical, or radio frequency (RF) domain. Construction: An electronically scanned array is a brick, stick, tile, or tray construction. Brick and tray refers to a construction approach in which the RF circuitry is integrated perpendicular to ...
The X band is the designation for a band of frequencies in the microwave radio region of the electromagnetic spectrum.In some cases, such as in communication engineering, the frequency range of the X band is set at approximately 7.0–11.2 GHz.
The pulse-repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit. The term is used within a number of technical disciplines, notably radar. In radar, a radio signal of a particular carrier frequency is turned on and off; the term "frequency" refers to the carrier, while the PRF refers to the number of ...
Advances in Radio Science is a peer-reviewed open access scientific journal published by the German National Committee of the International Union of Radio Science. It covers radio science and radio-frequency engineering. It was established in 2003 and its current editors-in-chief is Ludger Klinkenbusch (Kiel University). [1]
Radio Science is a quarterly peer-reviewed scientific journal published by Wiley-Blackwell on behalf of the American Geophysical Union and co-sponsored by the International Union of Radio Science. [2] It contains original scientific contributions on radio-frequency electromagnetic propagation and its applications (radio science).
Each year, since 1962, the M. Barry Carlton Award is given to the author(s) of the best paper to appear in the journal. The award was established in 1957 by the Professional Group on Military Electronics and initially given to the best paper to appear in the IRE Transactions on Military Electronics (1957–1962). [7]
