As a satellite passes overhead it sends out a radio signal that can be detected by a receiver in a car’s computer是定语从句吗?as和that的用法是什么?求帮忙分析一下句子语法

As a satellite passes overhead 是as引导的时间状语从句,下面是主句;
it sends out a radio signal 主句中:
that can be detected by a receiver in a car’s computer是that引导的定语从句,修饰radio signal

As引导的是时间状语从句,表示当.的时候,that引导的是定语从句,修饰a radio signal.翻译过来就是:当卫星经过上方,它发射出电波信号,该信号可以被车载电脑中的接收器检测到.
