本文介绍一种对半主动雷达寻的导弹杂波谱的仿真方法。文中给出了各种情况下的仿真结果,例如俯视、等高、仰视以及螺旋下降的目标等。仿真结果表明,俯视情况以及低空飞行所产生的主瓣杂波相当强,如果目标以适当的横向加速度机动,则主瓣杂波足以掩盖目标。本文考虑了产生这种掩盖效应的条件,并且通过仿真进行了验证。研究结果证明,主瓣杂波对导弹的有效攻击区影响很大。最后本文还提出了一种为避免上述杂波掩盖效应的制导方案。
This paper presents a simulation method of missile clutter spectrum for semi-active radar seeks. The paper gives the simulation results under various conditions, such as the top view, contour, looking up and the target of spiral descent. The simulation results show that the mainlobe clutter is quite strong when looking down and at low altitude. If the target is maneuvered with proper transverse acceleration, the mainlobe clutter is enough to cover the target. This paper considers the conditions for generating this masking effect and verifies it by simulation. The research results show that the mainlobe clutter has a great influence on the effective attack area of the missile. Finally, this paper also presents a guidance scheme to avoid the above-mentioned clutter masking effect.
