解釋
無線電定位-
So it holds a ideal ability to anti - interference and has 2 scalar level resolution in location and measuring velocity than traditional radio induction technology. and the channel composed of the new radio induction system for communication is different from the parameter - constant channel and the traditional parameter - changing channel, its parameter is decided by the mutual induction between its antenna and induction - cable, by the location of its antenna, by the signal frequency passing through, its parameter has nothing to do with the time parameter. the channel composed of the new radio induction system is a new parameter - changing channel independently of time for communication
而且，由新型無線感應系統組成的通道既不是恆參通道，也不是一般目前所知的變參通道，其通道傳遞函數的幅值只與信號的頻率有關，與系統中天線和感應電纜之間的互感和天線的位置有關，而與時間無關，其通道傳遞函數的相位只與天線的位置有關，而與時間無關，由新型無線感應系統組成的通道是一種不隨時間變化的新型變參通道。 -
