The variation ranges of species concentration, temperature and particle concentration of exhaust plume of the diesel engine with different load rate were tested in this article. Based on prototype experiment, the simulated generator and experimental platform of exhaust plume were built, and the effects of temperature, CO2, vapor and carbon soot on the infrared radiation characteristics of the exhaust plume were experimentally studied by infrared imaging. Experimental results showed that the temperature of the exhaust plume was the most important influencing factor for the infrared radiation characteristics, and the CO2 and carbon soot were also important influence factors too. However, the effects of the vapor could be neglected because of the slight influence on the infrared radiation characteristics of the exhaust plume.

“…So it has been widely applied to various armament devices [4] . At the same time, the accurate IR signature measurement of aircraft engines is paramount for designing [5] . Besides the real target, the targets management office also studies the low-cost, full-scale validated substitute targets in the experiment or simulation to serve for threat systems [6] .…”

A experiment of infrared characteristics of space target have been carried out in situ using ground equipments to better study the rule of the parameters related to the object characteristics. The experimental facility is realized in the laboratory. This facility serves two purposes, one is to verify the feasibility of the ground test for infrared characteristics of space target, and the other is to supply the required data for target characteristics simulations. The target characteristic ground experimental system consists of a space environment simulator, a space target simulator and infrared signal measuring apparatus. The space environment simulator afford an condition that the vacuum pressure is 10 -4 Pa, 80K , absorptivity about 0.9 radiation shield, and the radiation sources similar to the space environment. The different experiments based on different flight parameters of the same target were carried out like system engineering. The experiment results are consistent with the results of simulation and theory analyzing. The experiment is reasonable and efficient, which contributes to the research on the characteristic of target, and parts of the experiment system give a new method to the similar study.
