    • One embodiment of the present invention provides a system that characterizes a computer system parameter by analyzing a target electromagnetic signal radiating from the computer system. First, the system monitors the target electromagnetic signal using a first directional antenna located outside of the computer system, wherein the first directional antenna is directed at a location inside the computer system. The system also monitors the target electromagnetic signal using a second directional antenna located outside of the computer system, wherein a receiving axis of the second antenna is oriented non-parallel to a receiving axis of the first antenna, and wherein the second directional antenna is directed at the location inside the computer system. Next, the system characterizes the computer system parameter based on the target electromagnetic signal received from the first antenna and the target electromagnetic signal received from the second antenna. Then, the system generates a request for an action based on the characterization of the computer system.
    • 本发明的一个实施例提供一种通过分析从计算机系统辐射的目标电磁信号来表征计算机系统参数的系统。 首先,系统使用位于计算机系统外部的第一定向天线来监视目标电磁信号,其中第一定向天线指向计算机系统内部的位置。 该系统还使用位于计算机系统外部的第二定向天线来监视目标电磁信号,其中第二天线的接收轴定向成不平行于第一天线的接收轴,并且其中第二定向天线被定向 在计算机系统内的位置。 接下来,系统基于从第一天线接收的目标电磁信号和从第二天线接收的目标电磁信号来表征计算机系统参数。 然后,系统基于计算机系统的特性生成针对动作的请求。
