利用简单的无线电收发机,就可以实现隔墙看物!美国一所大学的科研人员在一个庭院中布置了一些普通的无线电收发机,组成了一种“无线网络”。当人走进测试区时,这些无线电收发机的电波强度会因人的出现而发生变化,这些电波数据通过成像技术显示在电脑上,就形成 The use of simple radio transceiver, you can see the wall! Researchers at a university in the United States arranged a few common radio transceivers in a courtyard to form a “wireless network.” When people walk into the test area, the radio wave strength of these transceivers changes due to the appearance of the human body. These radio wave data are displayed on the computer by imaging technology,
