We developed an impulse radio ultra-wideband (IR-UWB) radar-based system that can recognize alphanumeric characters in midair without the need for any handheld device. The hardware consists of four IR-UWB radar sensors set up with a rectangular geome

In order to avoid car crashes, active safety systems are becoming more and more important. Many crashes are caused due to driver drowsiness or mobile phone usage. Detecting the drowsiness of the driver is very important for the safety of a car. Monit

In this paper, we classify digits written in mid-air using hand gestures. Impulse radio ultrawideband (IR-UWB) radar sensors are used for data acquisition, with three radar sensors placed in a triangular geometry. Conventional radar-based gesture rec

Full-duplex radios have been receiving considerable attention due to their ability to simultaneously transmit and receive signals. However, the main challenge in full-duplex radio is the elimination of the self-interference (SI) signal, which is a tr

In this paper, we propose a new three-dimensional (3-D) shape reconstruction method for multiple aspects under sparse array topology and small fractional bandwidth of commercial radar chip in two-dimensional (2-D) multiple-input-multiple-output (MIMO
