MirrorSAR

A fractionated space radar for bistatic, multistatic and high-resolution wide-swath SAR imaging

This paper introduces the concept of a fractionated MirrorSAR which is based on a set of mutually separated transmitter and receiver satellites. As opposed to previously published bi- and multistatic SAR systems, the receiver satellites are considerably simplified, as their main ...
SAR instruments with multiple transmit/receive channels allow for a variety of operation modes. The trade-space includes the instrument and antenna parameters designed to enable various operation modes. These are utilized to achieve a required SAR performance derived from the mis ...
This paper reviews advanced SAR system architectures and modes for high-resolution ultra-wide-swath SAR imaging. The comparison includes both direct radiating array antennas and reflector-based system configurations operating in either a single-Transmit multiple-receive (SIMO) or ...
The architecture of framework to simulate Digital Beamforming reflector-based SAR systems is presented. The mai purpose of this tool is to allow the development and evaluation of DBF processing and calibration techniques unde realistic conditions. One of the main challenges is to ...
