基于IRIG 106固态记录器记录标准的PCM数据处理技术研究

Research of PCM Data Process Based on IRIG 106 Solid- state Recorder Standards

IRIG 106第十章是美军方靶场定义的固态记录器数据记录标准,已成为当前飞行试验主要记录技术;针对位流记录模式下PCM类型测试数据,文章提出PCM动态位流分析、即时PCM数据处理的新思路,并以miniR 700和MDR-8记录器卸载下的原始飞行数据文件为例,使用软件技术实现多PCM通道数据分路、PCM动态位流分析和数据处理;试飞数据处理结果表明,PCM数据动态位流分析、即时PCM数据处理思路可行,打破了传统PCM数据处理模式,数据处理效率比较高,可用于飞行试验数据处理。

IRIG 106 Chapter 10 instituted by US military ranges defines data recording formats of mlid state recorders, and becomes the main recording techniques in flight-- test. The dynamic bit-- stream analysis and instant process of airborne tK;M data recorded in bit stream mode are dis cussed. For raw data files downloaded from miniR 700 and MDR-- 8 recorders, software techniques are used to retrieve, analyze PCM hit- streams, and instantly process PCM data. The result of PCM data process shows that dynamic PCM bit- stream analysis and instant process of airborne PCM data break away traditional process mode of PCM data, are efficient and applicable to flight test data process.
