Research On Programmable Dynamic Target

A programmable dynamic target system is presented in this paper. On basis of analyzing the deficiency of traditional rotary target system, the significance and practicability of programmable dynamic target is proposed. Through obtaining the corresponding relationship between target and theodolite, simulation model that aims at founding the laws of the moving target produce influence on theodolite was set up. Electronics control system which including computer, uniform time circuit, interrupt circuit, PWM output circuit, power amplifier circuit and software etc was designed. Methods based on statistics for dimensional position and data processing were suggested for the calibration of the dimensional angle shown by a programmable dynamic target using linear matrix CCD and video interpretation. Studies in this paper show that the programmable target system is functional and capable of testing photoelectric theodolite. Consequently conclusions can be drawn that programmable dynamic target is new equipment to test photoelectric theodolite, not only can it check and test the performance, but also can measure the precision.
