Method of generating multiple SAR transmit beams and a SAR antenna system

摘要

The synthetic aperture radar or SAR system has a number of antenna elements (FE1-FE9) for generating transmission beams, within which several groups of antenna elements can be defined by circuitry, each with several adjacent antenna elements, whereby separate activation of a group of antenna elements is possible with the aid of circuit devices (2a-2d). The system has a reflector (1).
