| Abstract: | Based on image theory, this paper proposed a method to calculate the previous reflections, the first reflections and the second reflection, in AutoCAD. Using AutoLISP language, the path and delay time of the previous reflection can be obtained. This paper also introduced how to measure the previous reflection delay time of a receiver in a room. Compared the simulation and measurement, the reliability and feasibility are verified. |
