A 24GHz CMOS UWB Radar IC with IQ Correlation Receiver for Short Range Human Detection

A fully integrated 24 GHz UWB radar IC is presented. The IQ correlation receiver is employed for the detection fidelity and range extension. The transmitter is a VCO based impulse generator. The carrier frequency and bandwidth of the UWB signal can be tunable in the range of 21.8 - 24.5 GHz and 0.18 - 3 GHz, respectively. The equivalent sample resolution is 195 ps. The radar module using IC provides the maximum detection range for moving human up to 12.5 m within 120.27 mW power consumption.
