In the experiment, we build the laser diode radar ranging system, and use of the devices under different conditions of a large number of fixed-point ranging experiments.

So, this paper presents a more universal characteristics of the laser diode ranging evaluation system, and studies on laser diode characteristics of radar ranging in theory and experiment.

Based on the safety distance model, the software and hardware of the main control unit of sub-system and radar ranging of sub-system is designed, the key technologies is solved.
