Abstract: Two combination flight course modes, called parallel connection and series connection, are presented in this paper. Wecompared the characteristics and effects of them when multiple coordinated airborne early warning radars in use. In addition, thecoverage characters of different airborne early warning radar teams are analyzed, and they reveal that it is fitting for the airborneearly warning radars with blind zones. In the end, Authors point out how to optimize the connections in order to improve the detection effects.
