"There It has many possible applications in both the civil sector (remote detection, archeology, environmental studies) and the military sector", explains Olivier Ruault du Plessis of the Electromagnetism and RadarDepartment...

The DEMR (Electromagnetism and radardepartment) combines all ONERA's skills in electromagnetism and its applications for future radar and communication systems: ground or on-board radar, communications (space, aeronautical, terrestrial), radio navigation, electronic warfare (listening-in ELINT (electronic intelligence) or jamming)
"Time reversal offers us a means of creating strong fields with generators of limited power", says Florent Christophe, Assistant Director of Onera's Electromagnetism and RadarDepartment in Toulouse. Time reversal can concentrate the energy emitted by a generator over" a long" period (in reality, several microseconds) into a hundred or thousand times shorter period
"Its applications are multiple, in both the military and civil domains (remote sensing, archeology, study of the environment) "explains Olivier Ruault du Plessis of the Electromagnetism and RadarDepartment. Under the wings of the Falcon 20 are two pods with a carriage capacity of up to 250kg each which house the three high and low frequency radars, indispensable for airborne remote sensing operations, and which constitute the Sethi multi mode system
There are two reasons: the first, according to Jean Philippe Molinié, of the Electromagnetism and Radardepartment. We are mainly interested in the radar aspect: when a high frequency wave crosses the ionospheric layers, it is slightly deflected
It pursued its work in this field, developing experimental stealth measurement resources (BABI chamber), and studying stealth materials, while progressing in the fields of reconnaissance and very high optical resolution imaging, optronics and radar, with the synthetic aperture radar (RAMSES)... All same, these difficulties did not prevent it from developing very long range detection radars, in particular transhorizon radars
