编队飞行器的雷达角闪烁特性及其应用研究

Angular Glint of Aircraft Formation and Its Applications

针对作战过程中飞行器的规避拦截问题,从对抗制导雷达探测的角度,研究了飞行器编队作为扩展雷达目标的角闪烁特性及其应用问题。建立了编队飞行器N点散射源的角闪烁数学模型,利用相位梯度法计算了其角闪烁噪声的线偏差值及其分布特性。依此建立了4架飞行器通过不同编队模式与某典型地空导弹对抗的数学模型,并进行了数学仿真。仿真结果表明,飞行器通过合理的编队模式实现规避拦截是有效的。

The angular glint of aircraft formation was studied for avoiding it to be intercepted. The angular glint of the aircraft formation was modeled as an evenly distributed N-point scattering center, and the linear error of the angular glint and its distribution characteristics were calculated with the phase gradient method. A mathematical model of the apposition between four aircrafts in different formation modes and a typical surface-to-air missile was established. A simulation was performed by the model. The simulated result shows that it is effective to avoid intercepting with reasonable aircraft formation mode.
