In order to improve the identification capability of air targets and promote the efficiency of joint operations， a air target comprehensive identification method based on airspace coordination is proposed from the perspective of battlefield airspace control. The basic connotation， operational tasks and implementation methods of battlefield airspace control are introduced， and the internal relationship between air target comprehensive identification and battlefield airspace control is clarified. A brief description of the U.S. Forces air target hostile identification idea is given around airspace coordination measures， and introduces the basic concept， identification process and identification logic of air target comprehensive identification. Based on mathematical tools such as D-S evidence theory， the engineering application of air target comprehensive identification is investigated. The reliability of the method is verified by example calculations， which can provide some references for related researches.
