In the early 70s, ONERA launched into" the lowfrequencyradar" business following work on the characterization of reentry plasmas. ONERA quickly stood out thanks to the originality of its concepts and their experimental validation
That said, there are also fields in which Onera has knowledge that Thales lacks, in particular that of lowfrequencyradars... Onera's expertise remains essential for our development, just as it was for lowfrequencyradars... The frequency of the signals used is lower than that of traditional radars
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 lowfrequencyradars, indispensable for airborne remote sensing operations, and which constitute the Sethi multi mode system. "This facility, operational since 2008 and certified by the European Aviation Safety Agency, is unique in Europe, "confirms Olivier Ruault du Plessis, Manager of the Radar Imagery and Experimentation Unit of Onera
