Multi-Pass and Multi-Date At P and L Bands : Ground Penetration and Change Detection

Inhalt:
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 the latest upgrade of RAMSES and then presents the recent campaign which took place in Sweden, with simultaneous acquisitions at P and L bands. Data were acquired in multi-pass and multi-date mode in order to study ground penetration and change detection for these two bands. Moreover, the Sweden laboratory FOI acquired data at the same time in UHF and VHF bands [7-8] in order to complete the data set over the same scene.
