摘　　要：飞艇载干扰波束定向问题是影响对卫星通信地面站干扰效果的关键因素。文章对飞艇载天线指向使用地理坐标系到飞艇坐标系的变换算法,来消除飞艇姿态变化的影响;仿真和实践结果表明,应用此算法的天线波束指向精度较高。The interference beam directed on the aero boat is the key factor in interference to the satellite communication earth station. This paper applies conversion of coordinates from NED coordinates to aero boat coordinates to eliminate infection because of the change in aero boat gesture. Results of simulation and practice prove that this method improves the precision of beam direction.
