Our aim is to develop a microwave receiver antenna system, which can form its radiation pattern (main lobe direction, null-point direction, structure of the side lobes), measure the direction of the RF source in milliseconds. In this paper we will sh

An X-band SAR is developed, being upraded and tested. It uses solid state electronics and phase modulated impulses. The first results using corner reflectors prove the concept.
