mm-wave sensors

FMCW imaging radar at 94 GHz
Driven by the recent developments of low-cost, high-speed silicon technologies, (sub)mm-wave frequency systems (i.e., operating above 100 GHz) are receiving more research interest, with the promise to achieve higher performance than currently available in the fields of imaging (security and inspection) and sensing (material properties).

(Sub)mm-wave for imaging: The capacity to produce accurate images through obstacles at optical wavelengths (clothes, cardboard cartons, wood, thin walls) as well as during bad weather (fog and heavy rain), allows (sub)mm-wave systems to provide a smart “eye” to support security and transport applications.

(Sub)mm-wave for sensing: Provide higher resolution and sensitivity when measuring biological tissue composition, increasing the capability for early detection of diseases, leading to higher percentage of successful cure and lower probability of second intervention, resulting from intra-operation misjudgement.
