A novel matrix pencil-based interference mitigation approach for FMCW radars is proposed in this paper. The interference-contaminated segment of the beat signal firstly cut out and then samples cut-out region are reconstructed by modeling as a sum complex exponentials using pencil method to estimate their parameters. efficiency with different parameters (i.e. duration, signal-to-noise ratio (SN...

Hand gestures, being a convenient and natural way of communication, is getting huge attention for human–computer interface designs. Among these detecting mid-air writing one the most promising applications. Existing radar-based solutions often perform recognition by tracking hand trajectory using multiple monostatic or bistatic radars. This article presents multistream convolutional neural netw...

Highly accurate vibrometry and ranging are important topics in the industrialized economy. Wherever optical measurement technology fails due to its high prices vulnerability within harsh environments, millimeter-wave (mmWave) radar is well suited. This article introduces a signal processing chain for ultrawideband frequency-modulated continuous-wave (FMCW) radar. It uses fast-time evaluate inst...

Rotating radar sensors are perception systems rarely used in mobile robotics. This paper is concerned with the use of a mobile ground-based panoramic radar sensor which is able to deliver both distance and velocity of multiple targets in its surrounding. The consequence of using such a sensor in high speed robotics is the appearance of both geometric and Doppler velocity distortions in the coll...

This paper proposes a super-resolution-based direction-of-arrivals (DOA) estimation with wide array distance and extrapolation for vital frequency-modulated continuous-wave (FMCW) radar. Most super-resolution algorithms employ the between adjacent arrays of half wavelength, i.e., λ/2. Meanwhile, in case narrow field view FMCW radar, resolution angle is maintained by increasing spacing even if n...

With the increase in threats posed by small drones, development of radars to detect such drones has become a key necessity. In earlier studies, we proposed stationary point concentration (SPC) technique for drone detection using frequency-modulated continuous-wave (FMCW) radar. The SPC is novel approach mitigating leakage, which an inherent problem FMCW improves signal-to-noise ratio reducing n...

We present design and realization of a broadband FMCW Radar working in the Millimeter-Wave (MMW) region. The usable frequency range lies between 91GHz and 102GHz. We use a homodyne radar setup. Thus only one MMW source is necessary which is used for TX and LO generation simultaneously. The complex RX radar signal is calculated by a Hilbert transform in order to avoid a broadband MMW IQ mixer. A...

Microwave Radar is an attractive solution for forest mapping and inventories because microwave signals penetrates into the forest canopy and the backscattering signal can provide information regarding the whole forest structure. Satellite-borne and airborne imaging radars have been used in forest resources mapping for many decades. However, their accuracy with respect to the main forest invento...
