该论文设计了一款用于X波段合成孔径雷达（SAR）成像的4发4收脉冲线性调频相控阵雷达收发机（TRX），采用65nm CMOS工艺，每通道功耗253mW，旨在解决微型无人机或微卫星载荷对低功耗、小尺寸和高性能相控阵SAR系统的需求。
2 Airborne or spaceborne synthetic aperture radar (SAR) targeted for microunmanned aerial vehicles (UAV) or micro-satellites is capable of observing large area under all weather conditions with strong penetration, and finds many emerging applications in defence, geology, oceanography, agriculture and other areas [1]. Phased-array SAR, operating in three modes of spotlight, stripmap and scanSAR, can significantly improve the spatial resolution and detection SNR by steering the beams to the targets. The existing SAR system is still constrained by power, size, and performance for payload in micro-UAVs/micro-satellites. This paper describes the development of an X-band phased-array radar TRX IC achieving a power of 253mW/channel, and resolution of <30cm, with a die size
