In order to resolve the detection problem of passive remote weak targets under the background of strong interference
a detection algorithm based on adaptive beam space transformation using acoustic vector sensor array is proposed.Firstly
by designing a beamspace matrix which covers the observed sector and rejects the interference signals out-of-sector
the array output data are transformed to beamspace.Then
the generalized likelihood ratio test is derived in beamspace.The simulation results show that the method can detect the passive weak targets efficiently under the background of strong interference
and provide the constant false alarm rate(CFAR) detection.
