Abstract: In order to meet the requirements of the camouflage technology development in national defense engineering, this study analyzed the great challenges posed by high spatial resolution, hyper-spectral resolution, and real-time remote sensing technologies for those regular camouflage methods, based on features of remote sensing technologies and main exposure characteristics of national defense engineering. And then the major problems worth paying attention were pointed out. In addition, the application values of remote sensing technologies in supporting camouflage planning, improving camouflage effects, and developing new camouflage technologies were discussed, from the perspective of the advantages of remote sensing technologies for camouflage in national defense engineering. Thus the results of this study can provide some reference for research in this field.
