Abstract
A radio astronomy telescope with a wide field of view is an efficient tool for locating transient radio sources in space as supernova explosions. A promising method of designing this type of telescope is to apply Fourier transformation to the output signals from a phased array antenna. The implementation of a high-speed parallel FFT processor to an eight-element linear phased array antenna output is reported. Small size and low-power consumption are achieved by utilizing conventional digital video signal processing LSIs. In the pilot system, arithmetic operation up to a speed of 2.7 giga operations per second has been attained. The basic operation has been confirmed by solar observation.
