The document discusses the design of a new synthetic aperture radar (SAR) sensor for small satellites or μ-SATs. It aims to achieve a spatial resolution of 30m and a swath width of 30km within the size and power constraints of a small satellite payload. The design uses S-band frequencies, a 3m x 1m antenna, and pulse compression techniques to achieve the desired resolution while meeting μ-SAT limitations on dimensions, mass, and power. The proposed μ-SAR sensor would allow universities and small countries to develop and operate their own SAR satellites.
