Theory and test on nuclear quadrupole resonance explosive detection

LIU Zhao-he, WU Teng-fang, GU Wen-bin, GAO Pan(Engineering Institute of Corps of Engineers, PLA Univ. of Sci. & Tech. , Nanjing 210007, China; The First Engineers Scientific Research Institute of the General Armaments Department, Wuxi 214035, China)  
For solving false signal of landmine detection and realizing effective landmine detection,the basic principle of nuclear quadrupole resonance and its condition in explosive detection were introduced,and the resonant frequency and detection method of N14 nucleus in RDX and TNT were also analyzed. The actable experiment system for the explosive detection was presented. The free induction decay (FID) signal and its FFT transform of RDX,frequency response of RDX and the influence on detection signal in the case of different quantity RDX were particular researched and analyzed, and the system of test research on RDX realizes effective detection of RDX explosive.
