摘要

在最先进的调频连续波(FMCW)多输入多输出(MIMO)雷达系统中，天线通常是基于微带技术设计的。它们以均匀阵列排列，使得合成虚拟阵列最大化角分辨率。提出了一种基于基片集成波导(SIW)和非均匀平面阵列的77 ghz FMCW MIMO雷达前端天线和馈电结构的设计方案，并对旁瓣抑制进行了优化。提出了一种基于凸优化的MIMO阵列的设计方法，特别强调了副瓣电平抑制，并利用差分微带线到SIW的新过渡来馈送发射天线。测量结果表明，SIW和天线设计成功，雷达系统视场(FOV)内的副瓣电平为40 dB。

A 77-GHz FMCW MIMO Radar Employing a Non-Uniform 2D Antenna Array and Substrate Integrated Waveguides

In state-of-the-art frequency-modulated continuous-wave (FMCW) multiple-input multiple-output (MIMO) radar systems, antennas are usually designed based on microstrip technology. They are arranged in uniform arrays such that the synthesized virtual array maximizes the angular resolution. This paper presents the design of a 77-GHz FMCW MIMO radar frontend with antennas and feed structures based on substrate integrated waveguides (SIW) and non-uniform planar arrays optimized for sidelobe suppression. A design procedure for MIMO arrays with particular emphasis on sidelobe level suppression based on convex optimization is presented, and a novel transition from differential microstrip line to SIW is utilized to feed the transmit antennas. Measurements show the successful SIW and antenna design, as well as a sidelobe level of 40 dB within the field of view (FOV) of the radar system.
