Abstract:
1. A receiving apparatus configured to receive high frequency signals and to provide combined signals based on the received high frequency signals, the combined signals enabling generation of an image, comprising: two or more receiver channels, each receiver channel comprising an antenna pattern comprising plural antenna elements, the antenna elements being configured to receive high frequency signals; circuitry configured to: process the high frequency signals received by the antenna elements into baseband signals; perform analog-to-digital conversion to convert the baseband signals into digital signals; perform phase shifting of the digital signals; control the phase shifting to vary the phase shifts of the receiver channels such that receiving characteristics of the two or more receiver channels are controlled to form sharp antenna beams, and to move a position of the sharp antenna beams in at least one dimension of a first area of an image pixel space; and combine the phase shifted digital signals from the receiver channels into the combined signals, so that while the position of the sharp antenna beams is moved in the at least one dimension of the first area of the image pixel space, image formation of a second area of the image pixel space different from the first area is processed in a serial fashion.
