一种基于MDL原理的信号分选新算法
New Radar Signal Deinterleaving Algorithm Based on MDL Criterion
摘要
Abstract
A new radar pulse signal clustering algorithm based on inner‐pulse modulation characteristic is studied .The number of clusters in original data and the cluster that data vector belongs to is determined by clustering algorithm using the minimum description length (MDL) ,thus obtaining the number of ra‐dar emitters in the electromagnetic environment .The radar pulse data collected by the interception sys‐tem front‐end is treated as vectors and is sorted after the necessary pre‐processing .Pulse signals from different radars form different vector clusters after deinterleaving by using the algorithm based on MDL criterion ,because of their different inner‐pulse modulation characteristic .The largest advantage of the al‐gorithm is that it is unnecessory for quantitative analysis ,extraction and description of the inner‐pulse modulation characteristic .Simulation proves its effective .关键词
