摘　　要：由于不同型号飞行器的遥测数据帧格式复杂多变、形式各异,使得工作人员不得不频繁更动遥测数据仿真软件,尤其在面对新型号飞行器时,软件甚至需要重新开发。为此,提出了一种基于二态模型递归树的通用化遥测全帧数据仿真算法。首先,通过对遥测全帧数据的特点进行分析,提出了基于参数数据和结构数据的遥测全帧数据通用化二态表达模型,构建了描述遥测全帧数据的递归树,实现了遥测全帧数据通用化描述。其次,针对遥测全帧数据仿真问题,提出了基于多元函数递归运算的结构数据生成算法,并设计了参数反演算法,实现了遥测全帧数据的通用化仿真。最后,通过算例分析,验证了算法在遥测全帧数据仿真中的实用性和有效性。Due to complicated and volatile telemetry full-frame data formats for different types of aircrafts,the telemetry data simulation software has to be changed frequently.Especially for the new type of aircraft,the software even needs to be redeveloped.Therefore,a universal telemetry full-frame data simulation algorithm based on two-state model recursion tree is proposed.Firstly,by analyzing the characteristics of telemetry full-frame data,a universal two-state representation model based on the parameter data and the structure data is proposed.Based on the model,a recursive tree is constructed to realize the universal description of telemetry full-frame data.Secondly,in order to solve the simulation problem of telemetry full-frame data,a structure data generation algorithm using recursive operation of multiple functions is proposed,and a parameter inversion algorithm is designed.Finally,the practicability and effectiveness of the algorithm for the simulation of telemetry full-frame data are verified by an example analysis.
