机载预警雷达观测目标时受到载机姿态的影响，在仿真条件下估计载机姿态是一个难点。基于载机离散状态矢量，通过分析载机的运动与受力关系，建立用运动状态描述的载机姿态模型，提出一种实时性强，易于实现的载机姿态估计的方法。仿真和实测数据处理结果表明该方法既能有效用于仿真研究，在已知载机精确运动状态条件下也可以用来估计载机姿态。

Airborne early warning radar is affected by attitude when detecting. It is hard to estimate attitude in simulation. By analyzing the relationship between airborne dynamics and force, an attitude model described with airborne state is built and a method of airborne attitude estimation is presented. The method can be real time and easy to implement. Simu-lations and experiments of real measurements show that the method is effective not only for simulation but also for air-borne attitude estimation if its state is known.
