Abstract
- This paper presents a dual-mode intermediate frequency (IF) signal processing circuit for pulse compression radar (PCR) and symbol recovery. A half-duplex architecture is proposed to support modulation and demodulation of PCR signals. For data communication, the modulator and the demodulator support up to 3-Gb/s QPSK signal. For range sensing, the proposed IF correlation technique supports 1.5-GHz bandwidth (BW) and 3/5/7-b Barker codes for 10-cm range resolution. The circuit includes a high-linearity switch, a modulator, a reconfigurable demodulator/correlator, and an in-phase and quadrature clock signal generator. This proposed system is fabricated with 90-nm CMOS, and each channel can be configured to operate from 200 Mb/s to 1.5 Gb/s with different Barker codes. The maximum power consumption is 54 mW with 1.5-GHz BW (10 cm) in range sensing mode and 49 mW at a rate of 3 Gb/s in data communication mode. [ABSTRACT FROM PUBLISHER]
