In this study, an interference detection and mitigation method is proposed for frequency-modulated continuous-wave radar systems based on time-domain signal reconstruction. The uses the difference in one-dimensional fast Fourier transform (1D-FFT) results between targets interferences. 1D-FFT results, target appears as a peak at same frequency point all chirps within one frame, whereas absence ...

This study provides a solution for mm-wave FMCW radar-based heart-rate detection of an indoor moving person. The range-bin where the person is located will change during state, and signal energy weaker than clutter at farther distances. Therefore, we propose adaptive selection method that effectively selects optimal cell to obtain correct radar vital sign before heartbeat reconstruction. experi...

We propose a spiking neural network (SNN) approach for radar-based hand gesture recognition (HGR), using frequency modulated continuous wave (FMCW) millimeter-wave radar. After pre-processing the range-Doppler or micro-Doppler radar signal, we use signal-to-spike conversion scheme that encodes Doppler maps into spike trains. The trains are fed recurrent network, liquid state machine (LSM). read...
