核四极共振隐藏炸药探测信息库设计

利用核四极共振(Nuclear Quadrupole Resonance, 简称NQR)技术探测炸药时，实验复杂，参数繁多. 原子核参数、脉冲参数、环境参数等各参数对炸药共振频率及探测信噪比都有不同程度的影响. 针对长期以来国内外一直没有统一的炸药信息库，测试数据无法有效记录和管理的现象，在全面分析各参数与共振频率之间关系的基础上，设计并实现了隐藏炸药探测信息库. 该信息库能有效的收集和记录炸药参数信息，为今后炸药测试数据的统计分析提供统一规范的数据支持. 

An Information Database on Detecting Hidden Explosives with NQR-Based Methods

Many parameters need to be taken into account when using nuclear quadrupole resonance (NQR) to detect explosive, since the frequency and SNR of the NQR signals of the explosives are affected by the type of atomic nucleus of interest, the choice of excitation pulse and other parameters describing the test conditions. In the past, the NQR data of explosives could not be recorded and managed effectively due to the lack of a unified explosive parameter information database. In this study, a hidden explosive information database was designed and constructed after comprehensive analyzing the relationship between the testing parameters and the NQR frequencies of the explosives. The database can be used to collect and record parametric information of the explosives effectively, and will provide a useful platform for future NQR studies on explosives.
