Addressing Speed-Induced Dispersion in Stepped-Frequency PMCW Radar Systems

ICASSP 2025accepted

Phase-modulated continuous wave (PMCW) is a digital modulation waveform being investigated for modern automotive radar systems as a potential alternative to commonly used frequency-modulated continuous wave (FMCW) waveforms. In prior research, we introduced stepped-frequency PMCW (SF-PMCW), a varian…

A DNN Autoencoder for Automotive Radar Interference Mitigation

ICASSP 2021accepted

In this paper, a novel interference mitigation approach using an autoencoder in combination with a traditional interference detection filter is introduced. It is shown that by employing the gated convolution, the encoder has the ability to learn the signal pattern from the remaining interference-fre…

Automatic Radar-based Gesture Detection and Classification via a Region-based Deep Convolutional Neural Network

ICASSP 2019accepted

In this paper, a region-based deep convolutional neural network (R-DCNN) is proposed to detect and classify gestures measured by a frequency-modulated continuous wave radar system. Micro-Doppler (µD) signatures of gestures are exploited, and the resulting spectrograms are fed into a neural network.…
