Abstract: The implication of rocket exhaust plume signatures (such as the effects of noise, smoke,flame and heat radiation,environmental pollution and signal attenuation, etc.) and the great importance of studying these signatures are briefly explained in this review report. The progresses in research of rocket exhaust plume signatures are introduced and reviewed with the emphasis both on the theoretical prediction and on the practical measurement carried out in the world. The physical models of exhaust plume flow field and modeling technique, infrared radiation, primary and secondary smoke, as well as laser and microwave radar signal attenuation are mainly involved in this paper. The brief summary and further development of these studies are finally pointed out.
