Abstract

A UWB impulse radio (IR) timed-array radar using time-shifted direct-sampling architecture is presented. The transmitter array can generate and send a variety of 10GS/s pulses towards targets. The receiver array samples the reflected signal in RF domain directly by time interleaved sampling with equivalent sampling rate of 20 GS/s. The radar system can determine time of arrival (TOA) and direction of arrival (DOA) through time-shifted sampling edges which are generated by on-chip digital-to-time converters (DTC). The proposed architecture has range and azimuth resolution of 0.75 cm and 3 degree respectively. This prototype is implemented in a 0.18µm CMOS technology.
