PHARUS: a polarimetric C-band SAR

Abstract

A polarimetric SAR (synthetic aperture radar) system was designed in The Netherlands. The project is carried out in two steps. In this work, the first step, consisting of the preparatory studies including a SAR testbed, is described in detail. This SAR system will have limited capabilities, but will serve the purpose of acquiring experience with aircraft SAR and its technology. The system is built with state-of-the-art technology. Remarkable features are the fixed antenna and the low peak power, generated by solid-state devices. The use of monolithic microwave integrated circuits (MMICs) in the PHARUS was investigated in a preparatory study on antenna technology. Application of MMICs would further reduce the dimensions of the radar system.<>
