Indoor sensor array test-bed(SATB) for direction finding applications at communication-band

An efficient sensor array test-bed compatible with direction finding indoor test applications at communication-band is developed. It provides the test flexibility of DF accuracy including the different antenna configuration, DF algorithms and modulation schemes considering with instrumental errors induced by multi-channel receivers. The ability of test-bed is useful for system designers who are involved in the development of DF system at communication-band. Further research will be investigated the DF accuracy of FHSS and the effects of interference signal, frequency offset and integration time.
