Analysis of EMC of Pulse LRF

In order to resolve the problems of Electromagnetic Interference and improve the redundancy of electromagnetic compatibility in the high power pulse laser ranger finder, according to the operating principle of the laser ranger finder, we found the main source of Electromagnetic Interference in the laser finder, such as ： the laser exciter, control and information processor, control cable. Through theoretical analysis and calculation, this paper puts forward a solution concept and applies it to actual electric circuits. The result of experiment shows that the concept is feasible and can be implemented. The method can solve the problem of Electromagnetic Interference in the high power pulse laser ranger finder and can also lay a good foundation to expand the functions of the laser ranger finder.
