1996年9月24日《全面禁止核试验条约》（《全面禁试条约》）的签署和核查条约的国际监测系统的建立导致了利用次声监测技术探测核爆炸方面的迅速发展。IMS包括一个60个站点的次声监测网络，设计用于在两个或更多站点可靠地检测来自1千吨大气核爆炸的次声信号。这个网络中的电台均匀地分布在全球各地。每个观测站由一组高灵敏度微型气压计传感器组成，这些传感器以最佳配置排列，用于探测大气爆炸的信号。这一全球次声监测系统的建设已接近完成。在本章中，我们重点介绍了IMS次声阵列站的基本设计原则，重点介绍了阵列设计的最新发展、次声传感器技术的改进以及背景噪声降低方面的进展，这些都有可能提高全球网络的监测能力和可靠性。
The signing of the Comprehensive Nuclear-Test-Ban Treaty (CTBT) on 24 September 1996 and the establishment of the International Monitoring System (IMS) for Treaty verification has led to a rapid development in the use of infrasound monitoring technology for the detection of nuclear explosions. The IMS includes a 60-station infrasound monitoring network that is designed to reliably detect infrasonic signals from a 1-kiloton atmospheric nuclear explosion at two or more network stations. The stations in this network are located uniformly over the face of the globe. Each station consists of an array of high-sensitivity microbarometer sensors arranged in an optimal configuration for the detection of signals from atmospheric explosions. The construction of this global infrasound monitoring system is nearing completion. In this chapter, we focus on the fundamental design principles for IMS infrasonic array stations with an emphasis on the recent developments in array design, improvements in infrasound sensor technology, and advances in background noise reduction that can potentially improve the monitoring capability and reliability of the global network.
