This paper describes the design and verification of an ultra-wideband 6–14 GHz frequency modulated continuous wave (FMCW) primary radar system with very high range resolution. The design and measurement results of the utilized signal generator and receiver are presented. The signal generator features a 86% relative continuous tuning range and average phase noise of −106 dBc/Hz at 1 MHz offset to the carrier. The radar system utilizes a hybrid structure where the voltage controlled oscillator was fabricated using 130 nm SiGe BiCMOS technology and the lower frequency components are off-the-shelf. Free field measurements of the radar showcase an unprecedented combination of 3 cm range resolution, low phase noise and low operating frequency of 6–14 GHz for inherently higher range.

本文介绍了具有极高范围分辨率的6-14 GHz超宽带调频连续波（FMCW）主雷达系统的设计和验证。给出了所利用信号发生器和接收器的设计和测量结果。信号发生器具有86％的相对连续调谐范围，并且在相对于载波偏移1 MHz时的平均相位噪声为-106 dBc / Hz。该雷达系统采用混合结构，其中压控振荡器是使用130 nm SiGe BiCMOS技术制造的，而低频组件则是现成的。雷达的自由场测量展示了3 cm范围分辨率，低相位噪声和6–14 GHz较低工作频率的空前组合，从而固有地具有更高的范围。
