Abstract: Focusing on intelligentizing characterization for battlefield electromagnetic operational environment, firstly, the relations between cognitive operations and operational art are introduced, and operations in electromagnetic domain, electromagnetic spectrum operations and their correlated operations in the air, land, maritime, and space domains are analyzed. And then, based on the viewpoint of cognitive science and artificial intelligence, the requirements of the military tactical picture, common tactical picture and common operational picture for the characterization of battlefield electromagnetic operational environment are proposed. The real meanings of the layered cognition and intelligentized characterization, used for different commanders and staffs in full operation cycle, of battlefield electromagnetic operational environment are pointed out. Finally, the vision for intelligentizing battlefield electromagnetic operational environment characterization is set.
