射频接收机是现代电子系统中最重要的组成部分,应用在通信、导航等许多领域。射频接收机一般位于天线后端,直接发送和接收空间中的各种电磁信息。然而,由于接收机可以接收到任何信息,因此它也极易被干扰,如高功率噪声和电磁脉冲。首先分析了电子设备的电磁环境,然后主要以射频接收机为对象,将电子系统模块化建模,分析在空间环境中遭遇电磁脉冲攻击时的受损情况,最后通过系统建模仿真,分析了电磁脉冲对射频接收机后端系统的损坏情况。
射頻接收機是現代電子繫統中最重要的組成部分,應用在通信、導航等許多領域。射頻接收機一般位于天線後耑,直接髮送和接收空間中的各種電磁信息。然而,由于接收機可以接收到任何信息,因此它也極易被榦擾,如高功率譟聲和電磁脈遲。首先分析瞭電子設備的電磁環境,然後主要以射頻接收機為對象,將電子繫統模塊化建模,分析在空間環境中遭遇電磁脈遲攻擊時的受損情況,最後通過繫統建模倣真,分析瞭電磁脈遲對射頻接收機後耑繫統的損壞情況。

RF receiver is the most important part of modern electronic system,and widely applied in communication,navi?gation and other fields. Generally the RF receiver is located in the back?end of the antenna,and used to send and receive a variety of electromagnetic information in the space directly. Since the receiver can receive any information,it is also vulnerable to the interference,such as high power noise and electromagnetic pulse (EMP). The electromagnetic environment of electronic equip?ment is analyzed,then taking the RF receiver as the main object,and the electronic system is conducted with modular modeling. The damaged condition of the receiver attacked by EMP in the space environment is analyzed. The damaged condition coming from electromagnetic pulse to the back?end system of the RF receiver is analyzed by system modeling and simulation.
