法国ONERA RAMSES系统的最后一次SAR活动致力于各种应用，军事或民用，包括非常高分辨率，FOPEN（树叶穿透）与FOI， MTI合作，双基地SAR和植被表征。这些不同的项目使我们有机会改进我们的SAR处理程序（非常高的分辨率）并开发新的算法（双基地方案）。与此同时，ONERA团队开发并应用了许多技术（偏振分析、PolInSAR、小波分析），这些技术在这些不同的主题背景下被证明是有效的。目前的飞机平台，一架Transall C160将于2008年底退役。为了维持我们的活动，我们正在开发一个与小型飞机兼容的新系统系列。我们面临着两方面的挑战：将现有雷达迁移到小四倍的飞机上，并通过开发新雷达概念来保持我们的创新能力。本文介绍了SAR技术的最新成果，并描述了RAMSES后继者的发展现状：第一，SETHI，致力于军事应用和地球观测，第二，BUSARD更侧重于无人机应用。
The last SAR campaigns of the French ONERA RAMSES system have been dedicated to various applications, military or civilian, including very-high resolution, FOPEN (Foliage penetration) in cooperation with the FOI, MTI, bistatic SAR and vegetation characterization. These different projects gave us the opportunity to improve our SAR processing procedure (very high resolution) and to develop new algorithms (bistatic scenario). In parallel, the ONERA team has developed and applied many techniques (polarimetric analysis, PolInSAR, wavelet analysis) which proved to be efficient in these different thematic context. The current aircraft platform, a Transall C160 will be decommissioned at the end of 2008. In order to maintain our activities, we are developing a new system family compatible with smaller aircrafts. The challenge is two fold : migrating the existing radars in a airplane four times smaller and maintaining our innovation capabilities with the development of new radar concepts. These paper presents the most recent results on SAR techniques and describes the status of the development of the RAMSES successors : the first, SETHI, dedicated to military applications and earth observation, the second, BUSARD more focused on UAV applications.
