中文摘要:
      遥测数据误码直接影响飞行试验数据结果的分析和评估,建立合适的误码率模型对遥测数据处理的质量起着关键作用。本文在Rice衰落模型以及信号强度测距模型基础上对飞行试验多站数据进行分析,估计出接收端误码分布情况,得到了误码分布模型。从统计结果看出,遥测数据帧内误码分布为独立同分布,与位置无关,而帧间误码随飞行器与接收天线之间的距离减小而减少。多站数据误码分布的讨论为多站数据融合提供理论支持。
英文摘要:
      The error code of telemetry directly influences the analysis and evaluation of the test results. Establishing suitable error code model plays a key part in quality of telemetry data processing. The analysis of flight test data is based on Rice fading process and range based model of signal strength,and the error distribution model is obtained by estimating the distribution of the receiver. According to the statistical results, error code distribution of every bit in frame is independent and identical,and error codes of the receiver are becoming less and less with the aircraft approaching the antenna. Discussion on error code distribution of multi-station provides support for data fusion in theory.
