摘要

本文提出一种低频、空间定向及高灵敏的遥感方法。文中介绍了传感器及其二次仪表设计原理和关键技术。由作者研制的本检测系统

在空气中的定向接收灵敏度

离1米处高达120mV/μPa

比HP4905A型机的输出信噪比高8倍.

Abstract

A kind of remote sensing method with low frequency

high directivity and high sensitivity has been given in this paper. The principle and key technology for designing transducer and its secondary instruments have been presented. The directional testing sensitivity will be very high

such as 120mv/μPa over the range of one meter in the air. Signal-to -noise ratio for this system developed by the author is 8 times higher than that of HP 4905 A type.
