technical field [0001] The present application relates to the technical field of computer simulation, in particular to a simulation test method, device, computer equipment and storage medium. Background technique [0002] Computer simulation is a technique for simulating real-world things in a simulation system. Computer simulation technology can be used to check the effectiveness of computer algorithms in a real environment. In recent years, radar-based target detection can be applied in automatic driving or robot vision. In computer simulation technology, the radar system can be simulated to simulate the real working state of the radar system, and radar point cloud data can be provided for the test of the target detection algorithm. . [0003] At present, some simulated radar systems designed by simulation methods will add a small amount of noise to the propagation of the radar signal to simulate the attenuation of the radar signal when it propagates in the real environme...

Problems solved by technology

However, these simulation methods can only provide simulation results in good weather conditions, and cannot simulate the working conditions of the radar system in bad weather. However, in the real radar system, the attenuation of the radar signal is very large in bad weather such as rain and fog, which leads to the simulation results being different from the real ones. The situation is very different, and the simulation effect is poor
