Abstract

Abstract

The micro Synthetic Aperture Radar (SAR) system based on the traditional GaAs and GaN devices is not conducive to the monolithic integration, and the development bottleneck of volume, power consumption, weight and cost is becoming increasingly apparent, which is impossible to meet the needs of the miniaturized and ubiquitous unmanned platforms in the future. A new scheme for the design of a fully coherent Frequency Modulated Continuous Wave (FMCW) SAR with high resolution is proposed. The design method of high pulse phase stability and high isolation is studied and realized. The prototype of micro SAR is developed based on silicon chip and experimentally demonstrated. The micro SAR operates at K band, producing a signal bandwidth of wider than 2 GHz, enabling a range resolution of 7.5 cm. The system has made remarkable progress in terms of size, weight, power consumption and lay technical foundation for the monolithic integration of micro SAR system in a silicon chip.
