Abstract: 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.
