Technology of simulation for high-precision echo laser

Along with the expansion of application demand, the new generation of guiding system must be able to obtain rich information in the detection process, including angle and distance information. Therefore, laser ranging technology becomes a hot spot in the field of guiding field. In order to provide the simulation experimental conditions for laser ranging technology, a lot of works on laser echo simulation were done. In this paper, the development of the echo simulation system was described, which had the characteristic of angle and distance measurement for the laser ranging system. This system was named as laser echo simulator. The simulator could give the proper echo signal with a corresponding delay after receiving the trigger signal from the detection system. The echo characteristic and delay control capacity were analyzed. The hardware-in-the-loop system design was presented to verify the performance of laser ranging system. The experimental results indicate the feasibility of the system.
