Millimeter-wave (MMW) radar sensing, heralded as one of the most promising technologies for ensuring secure navigation in autonomous vehicles, is renowned for its high-resolution imaging capabilities and adaptability to diverse environmental and lighting conditions. This article presents a 3-D MMW imaging radar, which is specifically designed and employed for environmental mapping. It employs a full heterodyne detection technique, utilizing a sawtooth linear frequency modulated continuous wave (FMCW) approach with a central frequency of 94 GHz. Its minimum detectable radar cross section (RCS) is <tex-math notation="LaTeX">$-$</tex-math> 82.7 dBm, and its range resolution is 15 cm. Experimental comparisons of outdoor scenarios employing different antennas are conducted, and their performances are meticulously analyzed. These findings offer valuable insights into the application of MMW technology in the realm of environmental mapping.
