摘要

In this paper a D-band frequency modulated continuous wave (FMCW) radar system and a signal processing chain for vector network analyzer(VNA)-like S-parameter measurements are presented. The radar sensor covers an ultra-wide 56GHz (126GHz–182GHz, 36.4%) sweep bandwidth and can be equipped with a standard WM-1651 [1] (WR-6.5) waveguide flange. To achieve measurement-grade phase stability a cascaded...
