Abstract

The University of Massachusetts and the NASA Goddard Space Flight Center (GSFC) have jointly developed two synthetic aperture radiometers called Electrically Steered Thinned Array Radiometers (ESTAR-A and ESTAR-B). These sensors are five-element L-band interferometers designed as prototypes for future spaceborne systems that will provide high resolution imagery at a moderate cost by reducing the size of the antenna subsystem. ESTAR-A has horizontal polarization and was originally demonstrated in 1988. ESTAR-B is vertically polarized and is a second generation radiometer developed to improve on the design and performance of ESTAR-A
