Abstract: In order to design the material, which can generate the ultraviolet spectrum and fit a certain requirement, and measure the ultraviolet spectrum better, a method that utilizes some atomic material and appropriate excitation source to generate the needed ultraviolet spectrum and then measures the ultraviolet spectrum with the ultraviolet sensor is proposed.This is very useful for study and application of ultraviolet guided missile countermeasure and jam. According to related theories, the ultraviolet spectrum of atomic materials, especially the electron energy transition around alkali metal atomic nucleus is analyzed and calculated, and the spectral line data is listed in this paper. The measurement principle of target ultraviolet spectrum is also introduced. After the excitation scheme of suitable ultraviolet material is selected, the ultraviolet spectrum is measured with the dualgrating monochromator and ultraviolet sensor.Finally, the experimental result and the curve diagram of measurement for ultraviolet radiation spectrum are given.
