scanning antenna การใช้

QuikSCAT uses a dual-beam, conically scanning antenna that samples the full range of azimuth angles during each antenna revolution.
Scanning antennas, copper ribbons embedded like industrial jewelry in the glass, keep track of what you take in and out of the rooms.
The ISAT program is developing technologies that enable the deployment of extremely large electronically scanning antennas in space, and the metrology and calibration technologies necessary for coherent beamforming from such large antennas.
The AN / SPS-48E is capable of providing target range, bearing and altitude information using a frequency-scanning antenna using a range of different frequencies in F band with three power modes : high, medium and low.
Called synthetic aperture radar ( SAR ), an ordinary-sized antenna fixed to the side of an aircraft is used with highly complex signal processing to give an image that would otherwise require a much larger, scanning antenna; thus, the name synthetic aperture.
