摘　　要：针对空投技术的定位问题,提出了一种新的定位方法。首先,在空投目标区域放置发射机,发射天线在3个方向形成彼此相交的波束,发射机与3个波束的交点构成中心线,3个波束关于中心线对称。其次,发射天线在3个方向发射相同功率,不同频率的信号。最后,载荷上的接收机实时接收信号,经傅里叶变换得到信号频谱图。3个信号功率相等时载荷位于中心线上,保持现有飞行方向;3个信号功率不等时,根据偏离中心线的位置对飞行方向进行调整,确保载荷能够准确到达目标区域。该方法具有较高的定位精度,能够适应复杂电磁环境。Aiming at the positioning problem of airdrop technology,this paper proposes a new positioning method. Firstly,a transmitter is placed in airdrop target area,and transmitting antenna forms three beams intersecting with each other in three directions. The transmitter and three beams intersection forms the center line and three beams is symmetric. Further,transmitting antenna launches signals with the same power and different frequency in three directions. Finally,receiver on the load receives the signals and we can get the signal spectrum by Fouier transformation. When the power of three signal is equal,the load is located at the center line and keeping the current flight direction.When the power of three signal is unequal,the flight direction is adjusted according to the position of the center line and the load can reach to the target area accurately. This method has higher accuracy and can be adapted to complex electromagnetic environment.
