Non-destructive testing of arbitrarily shaped refractive objects with millimetre-wave synthetic aperture radar imaging [PDF]
Journal of Sensors and Sensor Systems, 2018 Millimetre-wave (mmW) imaging is an emerging technique for non-destructive testing. Since many polymers are transparent in this frequency range, mmW imaging is an attractive means in the testing of polymer devices, and images of relatively high ...
