摘　　要：先进作战飞机往往通过机动战术占据有利攻击位置,机载测向系统则会受机动状态影响。在机动状态下,论述载机横滚和俯仰变化对干涉仪测向误差的影响,通过坐标变换,明确载机姿态与测向误差的定量关系,推导误差计算公式,并以典型机载测向系统为例,仿真计算不同横滚和俯仰下系统测向误差。Advanced combat aircrafts often occupy favorable attack positions through maneuver tactics,the airborne direction-finding system will be affected by maneuvering state.The influence of roll and pitch variation of the aircraft on direction-finding error is discussed,when the aircraft is in continuous maneuvering state.According to coordinate transformation,the quantitative relationship between the direction-finding error and the roll and pitch angles of the aircraft is proposed,and the calculation formula is derived.The system direction-finding error is also simulated and calculated when the aircraft in different roll and pitch angles.
