mmSpy: Spying Phone Calls using mmWave Radars
IEEE Symposium on Security and Privacy, 2022This paper presents a system mmSpy that shows the feasibility of eavesdropping phone calls remotely. Towards this end, mmSpy performs sensing of earpiece vibrations using an off-the-shelf radar device that operates in the mmWave spectrum (77GHz, and ...

Experimental results from a fine-resolution three-dimensional (3-D) imaging method are presented. An object is flood illuminated with coherent light from a frequency-tunable laser. Electronic holograms are then recorded for a series of laser frequencies. These recordings are digitally assembled into a 3-D data array that is Fourier transformed to yield
