Contributions à l'étude des systèmes d'imagerie computationnelle interférométrique en bande millimétrique

Abstract : This work focuses on the transposition of interferometric computational imaging techniques to W-band. Based on the use of components that enable the multiplexing of signals in thephysical layer, these approaches greatly limit the complexity and cost of radar imaging systems. The constraints are then transferred to the digital layer, where increasingly powerfuland affordable computing solutions are now available. Carried out within the framework of the ANR Pixel, the aim of this work is to develop body scanners capable of revealing the presence of dangerous or illicit objects hidden under clothing. The central objective is to progress towards the development of thermal imaging systems operating at 90 GHz while limiting as far as possible the hardware constraints associated with the development of such scanners.
