A irborne remote sensing is an essential part of any surveillance system. Working for both defense and industry,ONERA constantly improves its radar and optical test platforms to help develop tomorrow's operating systems.

The SETHI-RAMSES NG platform supports applications such as the simultaneous collection of data from multiplesensors (SAR, GMTI, IR, hyperspectral, etc.), the development of new concepts, feasibility demonstrations underrealistic conditions and testing of models for industry.

SETHI-RAMSES NGMultispectral, multimode airborneplatform designed for radar

and optical sensors

SETHI-RAMSES NG

is an airborne system dedicated to remote sensing. It is composed of two pods placed under the wings ofa Falcon 20 operated by AVDEF. It combines high-performance SAR sensors as well as optronic sensors toexplore such concepts as:

• Long-distance radar imaging (> 70 km)

• Multi-frequency capacities (P-UHF, L, X bands)

• Wide area pushbroom or target designation mode

• Ultra-high resolution (centimeter) radar images

• Ground or foliage penetration imaging

• Moving target detection (GMTI, STAP)

• Polarimetry, tomography, circular imaging, interferometry, change detection…

SETHI-RAMSES NG

• Defence: intelligence, awareness, operation support

• Security: area surveillance

• Environment: climate, biomass, pollution...

Application fields

• Image/signature databases

• Knowledge of the environment

• Support for specification of future operational systems

• Industrial prototype testing

• Answers to ad hoc operational requests • Support to export cooperation policy

Products and outputs

• X-band, L-band and UHF radar sensors with polarimetric, interferometric and MTI capabilities

• Visible light and hyperspectral cameras

• Target designation system for sensor steering

Facilities

• A multifunction airborne platform offering radar / optronic synergy

• A flexible, modular and scalable "plug and play" platform, covering wide range of applications

• A world-class scientific team

• A customer-oriented approach with an offer tailored to each need
