Tools of Radio Astronomy (Astronomy and Astrophysics Library)Four significant factors have led us to update this text. The first is the breathtaking progress in technology, especially in receiver and digital techniques. The second is the advance of radio astronomy to shorter wavelengths, and the increased availability of astronomical satellites. The third is a need to reorganize some of the chapters in order... | | | | Phased Array Antenna Handbook, Second EditionPhased array antennas consist of multiple stationary antenna elements, which are fed coherently and use variable phase or time-delay control at each element to scan a beam to given angles in space. Variable amplitude control is sometimes also provided for pattern shaping. Arrays are sometimes used in place of fixed aperture ... |
