Abstract

Since the first report on our submillimeter-wave imaging system with radar ranging capabilities, several advances have been made in system performance. Range resolution as well as cross-range resolution are significantly improved, and image acquisition time has been reduced from over 5 minutes to under 1 minute. Here we report on performance improvements to specific key components and software that yielded these results. Further advances in these and other components will be discussed that we expect will enable, for the first time ever, near real-time 3D radar imaging at THz wavelengths.
