Coherent heterodyne FMCW lidar based on combined single/double sideband modulation detection technology
The conventional coherent FMCW lidar system has the problem of frequency drift to meet the high accuracy range. When measuring the moving target, it cannot judge the target motion status in real-time. This paper proposes a high-stability coherent heterodyne FMCW lidar detection method to solve the a...

520 | |a The conventional coherent FMCW lidar system has the problem of frequency drift to meet the high accuracy range. When measuring the moving target, it cannot judge the target motion status in real-time. This paper proposes a high-stability coherent heterodyne FMCW lidar detection method to solve the above-proposed problems. The combined single/double sideband modulation method significantly suppresses the frequency drift and, combined with the spectrum refinement processing method, achieves high stability of laser ranging and speed measurement. The result shows that the target is located at an 8 m distance from the system, the range accuracy is 5 cm, the range error is less than 1.5 cm, and the root mean square(RMS) error is 6.6 × 10-3 m, which is an order of magnitude higher than that of the conventional FMCW laser detection system. We use the binomial fitting method to obtain a measurement speed error of fewer than 1.15 × 10-2 m/s. | ||

Coherent heterodyne FMCW lidar based on combined single/double sideband modulation detection technology |
abstract |
The conventional coherent FMCW lidar system has the problem of frequency drift to meet the high accuracy range. When measuring the moving target, it cannot judge the target motion status in real-time. This paper proposes a high-stability coherent heterodyne FMCW lidar detection method to solve the above-proposed problems. The combined single/double sideband modulation method significantly suppresses the frequency drift and, combined with the spectrum refinement processing method, achieves high stability of laser ranging and speed measurement. The result shows that the target is located at an 8 m distance from the system, the range accuracy is 5 cm, the range error is less than 1.5 cm, and the root mean square(RMS) error is 6.6 × 10-3 m, which is an order of magnitude higher than that of the conventional FMCW laser detection system. We use the binomial fitting method to obtain a measurement speed error of fewer than 1.15 × 10-2 m/s. |
