摘要/Abstract

摘要：

针对基于核四极共振技术的爆炸物探测系统实际要求提出一种抑制振铃拖尾的天线设计方法. 该天线探头由高Q值调谐电路、阻抗匹配电路以及振铃拖尾抑制电路组成. 电路仿真结果表明，所设计的天线探头可以有效地抑制振铃拖尾，缩短天线的恢复时间，大大提高探测系统的可靠性.

关键词: 核四极共振(NQR), 爆炸物探测, 天线探头, 振铃拖尾抑制

Abstract:

To meet the practical demands for nuclear quadrupole resonance (NQR)-based explosive detection system, a probe was designed for suppressing the ring tails. The probe included a high Q- value tune circuit, an impedance matching circuit and a circuit for ring tails suppression. Simulation results showed that the proposed probe design can suppress ring tails effectively, shorten recovery time, and improve the reliability of the detection system.

Key words: nuclear quadrupole resonance(NQR), explosive detection, probe, ringing suppression
