Abstract

En fremgangsmåte og anordning for å redusere fransientvirkningen av sfrålesvitsjing i et antennesystem med sfrålesvitsjing beskrives. Et antennesystem med svitsjet sfråle genererer flere sfråler i et forhåndsdefmert sfrålemønster og svitsjer den nåværende stråleposisjonen til en av de flere forhåndsdefinerte sfråler i samsvar med måle- resultater for hver av strålene. Signalenes kvalitet måles periodisk for hver av de flere forhåndsdeflnerte sfrålene, og den beste sfrålen bestemmes. Den nåværende sfrålen svitsjes til enten den beste sfrålen eller en mellomliggende sfråle i henhold til separasjonen mellom den beste strålen og den nåværende sfrålen.
