摘要
ADAS-汽车驾驶辅助系统正在当前的汽车市场中迅速普及。车载雷达作为ADAS系统的重要组成,其技术发展直接影响着汽车智能化进程。毫米波雷达因为其波长的物理特性不受恶劣的环境影响,同时相比激光雷达又有较大的价格优势,已经成为当前厂家的首选。与24 GHz传感器相比,77 GHz传感器的分辨率和精度更高,体积小,正逐渐成为当前汽车领域的主流传感器。同国外雷达传感器供应商相比,国内车载毫米波雷达仍属于起步阶段,国内企业要在市场上与外企竞争并占有一席之地还有很长的路要走。
ADAS is widely used in automobile market. Because of the physical characteristics of its wavelength, millimeter wave radar sensor can adapt to the rainstorm, fog, night driving and other harsh environment. At the same time, compared with laser radar, it has a greater price advantage, and has become the first choice of current manufacturers. Compared with 24 GHz sensor, 77 GHz sensor has higher speed resolution and accuracy, smaller volume, and is gradually becoming the mainstream sensor in the automotive field. Compared with foreign radar sensor suppliers, domestic vehicle borne millimeter wave radar is still in its infancy. Domestic enterprises have a long way to go to compete with foreign enterprises and occupy a place in the market.
