Abstract:

This paper aims at the problem that it is difficult to evaluate the angle tracking error performance of the dual stealth aircraft formation when the monopulse radar detects and tracks the cooperative jamming state. For the first time, a non coherent jamming model of cooperative scintillation of stealth aircraft based on the horizontal flight path of two side aircraft formation is established. After solving the formation attitude under the same track, the dynamic radar cross section (RCS) sequence of formation under the scintillation jamming model is obtained. Combined with the angular tracking characteristics of monopulse radar tracking model in the scintillation jamming model of dual aircraft formation, the angle error of monopulse radar corresponding to the scintillation jamming of dual aircraft formation is deduced. The difference tracking model takes the minimum effective decoy angle as the real-time parameter to evaluate the change degree of radar angle tracking error performance under the glint jamming mode. The simulation results show that the angle error of monopulse radar can be effectively increased by 5.67 times and the angle tracking of monopulse radar can be effectively induced in the phase of jamming release.

Key words: dual stealth aircraft formation, blinking jamming, monopulse radar, angle tracking error
