Abstract

The addition of potassium salt to the propellant of aircraft can effectively reduce the secondary combustion of the wake flame and the difference between the background radiation, which makes the targets detection more difficult for traditional infrared method. Based on high-spatial-resolution, high-throughput and compact spatial heterodyne spectroscopy(SHS), the dynamic target monitoring spectrometer(DTS)detects the potassium spectral lines of 766.49 nm and 769.90 nm by combining the one-dimensional spatial imaging with the two-dimensional orthogonal detection mode. The spectral range and resolution of the two channels of DTS were calibrated by the hyperspectral monochromatic uniform light source scanning system. The relative response consistency correction and absolute response coefficients of the two channels were calibrated by using the large-aperture integrating sphere, and the target spectral lines were extracted by background difference and target spectral line isolation. The target spatial was located and spectrum synthesis was carried out according to the spectral and radiation calibration results and the corresponding relation of the two-dimensional field of view. Finally, a complete data processing flow of DTS is established. In order to test the DTS developed by the laboratory, the target was simulated by adding K2SO4 to the burning alcohol in the outdoor environment. The detected target was successfully recorded through two-channel spectrum synthesis, showing the dynamic change process under the influence of outdoor wind during the combustion process, which verified the rationality of the processing flow.
