摘要
At present, laser radar is main studied in the in automotive sensing. However, Driverless cars have higher request for different environment and light conditions. It is even difficult for lidar to find tiny targets on the road, such as pits and packets. In the paper, The low-terahertz high-resolution imaging radar system operating frequency is 94GHz, Using the frequency-modulated continuous-wave (FMCW) technique with 3mm wavelength. We simulated the pits of different depths on the road, analyzed the changes in the electromagnetic field, and used the low-terahertz radar to perform experiments.
