Method and system for calculating aircraft descending deviation curve

The invention discloses a method and a system for calculating an aircraft descending deviation curve. According to the method, the azimuth and pitching data of a tracked aircraft target are transmitted back in real time by virtue of special rotary table equipment mounted in an airport, the descending process of the aircraft target is tracked for multiple times, and a standard descending curve during target descending is extracted according to the azimuth and pitching relationship during aircraft descending. When the aircraft descends, the azimuth pitch value of the aircraft is recorded in realtime and compared with a standard curve, the offset of the aircraft can be obtained, real-time azimuth pitch information when the aircraft descends is drawn and compared with standard descending lineinformation, the deviation condition of the aircraft when the aircraft descends is obtained, and the yaw state of the aircraft is obtained in real time. 本发明公开了一种飞机下降偏离曲线的计算方法及系统，本方法依靠安装在机场的专用转台设备，实时传回所跟踪飞机目标的方位、俯仰数据，多次对飞机目标的下
