초고속 이동체 탐지에 적합한 초광대역 CMOS RFIC 기반 레이다 시스템

Abstract

This paper presents CMOS UWB RFIC based radar system for high speed target detection. The system can achieve resolution of 15 cm and detection range of 15 m. For developed system, single chip CMOS UWB IC is implemented. To reduce the measuring and processing time, envelope detection and equivalent time sampling technique are used. Measurement results show that the bandwidth and center frequency of UWB pulse can be adjusted in the range of 0.5 GHz∼1.0 GHz, 3.5 GHz∼4.5 GHz, respectively. Signal processing time including scan time over 15 m distance is about 150 μsec.
