A Subharmonic Super-Regenerative FMCW Radar With Improved Intermodulation Efficiency for Applications Beyond Cut-Off Frequency

This article presents a novel subharmonic super-regenerative receiver (SHSRR) radar for high-sensitivity and low-noise operation in beyond- f_\text{max} frequency-modulated continuous wave (FMCW) applications. In contrast to conventional super-regenerative designs, the proposed concept is extended...
