Printed reflectarray antenna for space-based SAR

More and more stringent requirements are being imposed on antenna systems used in earth remote sensing. One of these antennas is a reflectarray antenna, which combines the advantages of a reflector and a phased array antenna. However, such antennas are more often used in radio communication systems, and the possibility of using this type of antennas in space-based synthesized aperture radars is rarely considered in literature and articles. In this article, the results of research work on an antenna with a flat reflective array are considered and an assessment of the feasibility of using it in systems with synthesized radar on small spacecraft is carried out.
