在新型飞机飞行试验中,经常采用两套光电跟踪测量系统对飞机及投放物、带动力或无动力飞机模型等小范围试验科目进行轨迹测量,在传统的测量模型基础上对其数学模型进行了改进,提出了一种新的附有观测约束条件的数学模型以及算法。飞行试验证明,该算法能够有效提高观测数据处理精度。
In the new aircraft flight test, two sets of photoelectric tracking measurement system are often used to measure the trajectory of small-scale test subjects such as aircraft and launch vehicle with or without powered aircraft model. Based on the traditional measurement model, the mathematical model is carried out Improve and put forward a new mathematic model and algorithm with observational constraints. Flight test proves that the algorithm can effectively improve the accuracy of observation data processing.
