摘要:

针对单脉冲雷达检测跟踪协同干扰状态的双隐身飞机编队时,角度跟踪误差性能难以合理评价的问题,首次建立了基于侧双机编队平飞航迹的隐身飞机协同闪烁非相参干扰模型,经过相同航迹下编队姿态的解算,获取闪烁干扰模型下的编队动态雷达散射截面序列,结合双机闪烁干扰模型下单脉冲雷达角度跟踪特点,推导得出与双机编队闪烁干扰相适应的单脉冲雷达角度误差跟踪模型,以最小干扰有效诱偏角为实时参变量对闪烁干扰模式下雷达角度跟踪误差性能变化的程度作出了评价。仿真表明双隐身飞机闪烁非相参干扰在干扰释放阶段能有效使单脉冲雷达角误差提高5.67倍,有效诱偏单脉冲雷达的角度跟踪。

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
