The ONERA RAMSES system is a flexible SAR system in constant evolution, developed mainly as a test
bench for new technologies and to provide specific data for TDRI (Target Detection, Recognition and Identification)
algorithm evaluation. It is flown on a Transall C160 platform operated by the CEV (Centre d'Essais en Vol).
In this article we compare the SRTM X-SAR DEM and the ONERA's RAMSES SAR sensor DEM over the
same area: the St Mandrier peninsula in south of France. Our study is composed of two parts: after a brief description
of our sensor we firstly present a global assessment over the peninsula and secondly we focus on the large buildings to
evaluate the detection and measurement capabilities of the SRTM products.
The ONERA RAMSES system is a flexible SAR system in constant evolution, developed mainly as a test
bench for new technologies and to provide specific data for TDRI (Target Detection, Recognition and Identification)
algorithm evaluation. It is flown on a Transall C160 platform operated by the CEV (Centre d'Essais en Vol). This
paper gives an overview of the system, lists briefly the latest upgrading (electronic and SAR processor) to acquire
high resolution data without deramp-on-receive mode and then presents the recent campaign which took place in
Sweden, with simultaneous acquisitions at P and L bands.
