嵌入式大气数据传感系统误差分析

Error analysis on flush air data sensitive system

嵌入式大气数据传感(FADS)系统与传统大气数据传感系统相比,其精度、适用范围、可靠性等都具有优势。在应用之前,对其在应用中存在的各种误差进行建模、仿真,以了解各种误差对FADS系统精度的影响。之后设计蒙特—卡洛仿真,为沿某一条飞行轨迹进行误差分析提供了一种可行的方法。该方法可用于分析不同算法在不同飞行条件下的精度,为FADS系统算法选取提供参考。

Compared with traditional air data sensitive system,flush air data sensitive system(FADS)is more accurate,and more reliable,and can be used in wider range.Before the application,it is a good idea to build the error models existing in application,and to carry out simulations to know how the errors affect on the FADS system precision.Then,the Monte-Carlo simulation is designed to provide a feasible method for analyzing errors along a flight trajectory.The method can be used to analyze precisions under different algorithms under different flight conditions to provide reference for algorithms selection for FADS system.
