Influence of Channel Count and Array Sparsity on the Detection Performance of 4D Imaging Radars

IEEE Journal of Microwaves
Separability, detection capability, and height estimation performance are key measures of high performance 4D imaging radars. While many different sensors have been presented in recent years, no sensor-independent comparison of the performance achievable

Over-the-Air Phase Noise Spectral Density Measurement for FMCW Radar Sensors

IEEE Journal of Microwaves
Phase noise significantly degrades the performance of frequency-modulated continuous wave (FMCW)- and chirp sequence (CS)-based radar sensors. Knowledge of the power spectral density (PSD) of these sensors is therefore essential for estimating their ...
