摘要：Radio-signal direction finding has been performed as follows. There is mutipleantennas (one) in different positions. Switchable antenna coupling device (SAC) switch(SW) is couple to input (INP) from an antenna (radio signal of A [i]) and is couple to radiosignal input (INP) to another antenna (A [i+1]). Which is present in radio signal input (INP)to obtain phase-detection input signal (PDIS) for a kind of radio signal processor (ASP)processing radio signal (AS). A kind of A [i] () (A [i+1]) of the phase-detection input signal(PDIS) of phase-change detector (PCD) detection Δ ζ (phase transformation) due toswitching (SW) from an antenna to another antenna. Calculator (CAL) calculate thedirection radio-signal source (SRC) (DIR) based on the phase transformation (Δ ζ). Thisradio signal that executes finds that the cost with rather moderate can be implemented,because it only needs a radio signal processor. It is particularly well suited for being usedin wireless communication device, for example, selection, the antenna will provideoptimum signal quality.
