一种面向雷达辐射源全要素数据的索引方法
An Index Method for All Factor Data of Radar Radiation Source
摘要
Abstract
According to massive spatial-temporal data and high probability of queries by granularity in reconnaissance field,an index method for all factor data of massive radar radiation source is proposed and the method utilizes the multi-granularities and multi-level spatial-temporal data model.Chord protocol and B+-Tree are combined to index data according to time dimension and R-Tree is used to index data according to spatial dimension.Region coding sequence is introduced in tree R.The calculations of"AND"and"OR"between sequences are utilized to form tree RCR suitable for the query of regional granularity.In addition,RowKey is designed depending on the characteristics of index and data to make it easy to store and query data in HBase.Two phases indexing mechanism is proposed to reduce the cost of updating data in real time and to improve the efficiency of querying historical data.At the same time,according to the correlation relationship of all factor data for radar radiation source,the search efficiency of track data to IF data is improved.Finally,the efficiency and the scalability of the proposed method are verified by experiments.关键词
