In order to carry out omnidirectional, large deep early warning detection of the enemy`s key attacking areas, multi-AWACS cooperation will be studied based on the Doppler blind zone map. The restricted detection area and Doppler blind area are two main factors that affect the detection ability of AWACS aircraft. Considering the important role of the relative radial velocity inflected on the Doppler detection performance of the AWACS, this paper revealed the reasons and changing rules of the relative radial velocity blind area, which are helpful to improve the efficiency of early warning and control aircraft target detection. This paper proposed the definitions of Doppler blind zone and area blind speed probability, and the detection capability of AWACS under two different patrol routes was analyzed. The analysis process can verify the rationality of the results of early warning aircraft route planning, which can significantly guide for early warning aircraft task planning.
