摘要

A 65-nm CMOS, 18-mm2, 1.5-GHz 64 × 64 crosscorrelator with 128 on-chip analog-to-digital converters (ADCs) enables real-time synthetic aperture radiometric imaging. This brief enables high-resolution synthetic aperture radiometry by greatly improving the integration and energy efficiency of the mixed-signal baseband cross-correlator. The design supports analog-in and digital correlation out, remov...
