Abstract :
A new 24 GHz non-linear FMCW radar is reported, which features a high-precision 2.45 GHz SAW (Surface Acoustic Wave) reference and adaptively compensates for phase errors by software. Kernel functions are implemented at a 2.45 GHz IF level reducing the expense of critical RF components in order to realize a fully planar front-end.
