实时无失真雷达数据压缩新算法

研究了雷达测量系统对运动目标进行精确识别和跟踪中的数据压缩技术，首先求出了不依赖信源统计特性的预测系数αｉ，并给出了一个判决定理。然后，以预测技术为基础，提出了两个对相关性较强的数据进行实时无失真压缩的新算法，并从编码速度，时延，误码扩散，自同步和压缩比等方面进行了讨论。

New Algorithm for Real Time Lossless Radar Data Compression

The data compression technique was studied,which is used in radar measure systems to identify and track moving targets precisely.First,linear predication coefficients a i which are independent of statistical feature of signal source were evaluated and a decision theorem was proposed.Secondly, two new methods based on predication technique were introduced to real time lossless compression for data with significant correlation.Coding speed,time delay,error bit propagation,self synchronozing and compression rate were also discussed. Simulation test showed that the new algotithms were superior to existing algorithms.
