The influence of the navigation direction of the dual stealth aircraft formation on the performance of monopulse radar

Aiming at the problem of how to effectively compare and analyze the influence of the angle tracking error of monopulse radar caused by the difference of the dual stealth aircraft formation in the formation navigation direction, the dynamic track model of the dual stealth aircraft in different navigation directions is established for the first time, and the acquisition method of the dynamic RCS of the formation under different navigation directions is put forward. Using the time-varying dynamic signal-to-noise ratio of the dual stealth aircraft in different flight directions as parameters, the monopulse radar angle tracking error solving model suitable for the cooperative flight of dual stealth aircraft is established. This paper analyzes the influence of the difference of the dual aircrafts’ heading direction on the angle tracking error performance of monopulse radar. It is the first time to conclude that the angle tracking error of monopulse radar will increase obviously with the increase of the heading angle of dual stealth aircraft when there is no interference.
