Abstract
Laser ranging systems will be affected by electromagnetic sensitivity effects in complex electromagnetic environments, and it is difficult to determine which interference signals have the greatest impact on the system in complex electromagnetic environments. Moreover, it proves difficult to simulate a complex electromagnetic environment in an electromagnetic compatibility experiment. In view of the above problems, this paper takes the laser ranging system composed of VL53L0X laser ranging sensor module as the research object, and designs a sensitive experimental platform based on the laser ranging system. Using the experimental platform of this system, different interference signals are injected into the laser ranging system to simulate the complex electromagnetic environment. By analyzing and researching the data of experiments, the sensitivity threshold curve of the laser ranging system under different interference signals is obtained, and the sensitivity model of the laser ranging system is determined to be peak-sensitive, which means it is more sensitive to the amplitude modulation signal of the modulation depth.
