我下载了你提到的Wifi Radar并尝试了它。这里有一个重要的步骤——它要求你在将设备握在身上的同时原地旋转一会儿。
所以我的猜测是它使用内部指南针来确定你指向的方向，然后测量信号。当信号变强时，表明您正在指向 AP。
由于该应用程序要求您将设备靠近身体，因此它试图将您用作盾牌，因此如果您背对着接入点，您的身体会削弱信号。
I downloaded Wifi Radar that you mentioned and tried it. There's an important step there - it asks you to rotate on the spot for a bit while holding the device to your body.
So my guess is that it uses the internal compass to figure out which direction you're pointing to, and then measures the signal. When the signal gets stronger, it figures that you're pointing toward the AP.
Since the app asks you to hold your device to your body, it's trying to use you as a shield, so if you're facing away from the AP, your body will weaken the signal.
