CMOS nanoscale impulse radar utilized in 2-dimensional ISAR imaging system

This paper presents a complete impulse based radar transceiver integrated on a single chip. The high bandwidth of the transmitted pulses offers unique penetration abilities and very high accuracy. By taking advantage of the Continuous Time Binary Valued (CTBV) design paradigm, some of the main show stoppers of systems based on traditional digital design techniques have been removed. This paper explores the advantages and possibilities of the fully integrated CTBV radar, and introduces basic background on the Inverse Synthetic Aperture Radar (ISAR) along with experimental results. Measurements have been performed that confirm the theory and show that the proposed nanoscale impulse radar system may be utilized for 2D-imaging combining low cost implementation with high quality. The CMOS radar consumes 113mW from a 1.2V/2.5V power supply.
