A Novel Method for Speech Acquisition and Enhancement by 94 GHz Millimeter-Wave Sensor
Sensors, 2015 In order to improve the speech acquisition ability of a non-contact method, a 94 GHz millimeter wave (MMW) radar sensor was employed to detect speech signals. This novel non-contact speech acquisition method was shown to have high directional sensitivity,

Real-Time Signal Generator for Noise Radar
IEEE Aerospace and Electronic Systems Magazine, 2020 We present a real-time intermediate frequency noise radar signal generator that provides pseudo-random signals with uniform, normal, exponential, and Rayleigh probability distributions. In addition, normally distributed samples with uniform power spectral distribution with arbitrary bandwidths can be generated. The noise signal generator is implemented
