The mathematical model of the time of flight to accomplish electronic analog computing is introduced in this paper,and the distance scale transform is specified by taking the optical ranging as an example.The the method of com- puting the time of flight is illustrated by using some basic calculating circuits such as the addition circuit,the inversion circuit and the division circuit.The electronic analog circuit simulates the time of flight,and in the circuit the continu- ous variable corresponds with prototype physical quantity.In this way it provides advantages for the gun sight to form the total correction angle by giving high calculating speed,high precision and strong logical function.
