摘　　要：信息社会的发展愈演愈烈,电磁信号的传输安全性要求日渐提高,使得对环境中的电磁或者针对单一设备的发射电磁波作检测、接收及分析定向显得尤为重要。本文以智能手机为平台,提出了基于Android的信息电磁发射波捕获和搜索系统的软件设计和实现方案,成功实现了对调频电台所发射的无线电磁波的捕获和搜索定向,并搭建了专门的测试场景用于对其的功能测试,给出了实际场景下的测试结果,在一定程度上填补了当前国内在Android平台上相关领域研究的空白。With the rapid development of the information society, the high requirements of transmission safety of electromagnetic signals, it is very important to detect, recept and analyze the leakage of electromagnetic wave in environment or the emitting electromagnetic wave from a single device. This paper proposes a route of software design and realization of an information electromagnetic emitting wave capturing and searching system based on smart phone, which successfully realizes the capture and direction search of wireless information radio frequency electromagnetic energy emitted by the FM radio. This paper also builds specialized test scenarios for the functional test and thereby the test results are given. The research and realization of the system can ifll the gaps for the platform of Android in relevant ifelds inside the country in a certain extent .
