Live Demonstration: A Ku-Band Fmcw Synthetic Aperture Radar Transceiver For Micro-Uavs

This live demonstration presents a first-in-kind fully integrated Ku-band Synthetic Aperture Radar (SAR) transceiver chip in 65-nm CMOS that fits for micro-UAVs. The transmitter presents 13.3-dBm output power and 1.48 GHz chirp bandwidth centering at 15 GHz. The receiver front-end attains 23.5-dB gain, -33-dBm IP1dB and 5.6-to-6.3dB noise figure. The receiver analog baseband achieves 0.68-to-9.8-MHz programmable passband and 55-dB variable gain range. The integrated ADC has 9.4-bit ENOB. The SAR chip achieves super-resolution of 11.2 cm and consumes only 260-mW power. The ranging and imaging functions of the prototype are showcased.
