摘要
研究中程警戒雷达仿真中飞机编队平均雷达反射截面的实时计算问题。首先运用经验曲线计算单架飞机处于不同姿态角时的平均雷达反射截面。其次当飞机在飞机编队中被遮挡时,考虑对飞机平均反射截面起主要作用的因素:飞机的投影面积、进气道、座舱和雷达舱;然后利用简化的飞机模型,计算飞机被遮挡与没有被遮挡时这些因素对反射截面贡献的比例,从而计算出被遮挡飞机的平均雷达反射截面。最后将飞机编队中各架飞机的反射截面相加,就可以得到飞机编队总的反射截面。
A real-time calculation method of RCS for formation of aircraft is studied. The method is applied to search radar simulation. First, based on an experiential curve, a simplified method of calculating Radar Cross Section (RCS) of aircraft in any attitude angle is presented. Second, when a aircraft is sheltered in formation of aircraft, some aspects that chiefly contribute to RCS are considered, which are projection area, open cavity, capsule cabin and radar cabin. Based on a simplified model of aircraft, a proportion that these aspects contribute to RCS when aircraft is sheltered and unsheltered can be calculated. Then the RCS of a aircraft which is sheltered can be calculated. Finally, adding the RCS of every aircraft in formation of aircraft is the RCS of formation of aircraft.
