Research on echo receiving circuit of proximal fuse laser rangefinder

The laser proximal fuse is used to detect objects with laser beam. It can conduct a comprehensive survey of objects and has the characteristics of good anti-interference, accurate directionality, and high precision. Aiming at some common problems of proximity-fused laser rangefinder, a new echo receiving circuit of the system was designed in this paper. What´s more, the performance of the system were simulated and analyzed in-depth. The key parameter was met with the system requirement. The designed echo receiving circuit was used in practical laser ranging system.
