摘要: In this letter, we consider the problem of direction detection in deterministic interference and partially homogeneous noise. The target echoes, reflected by a distributed target, all come from same direction. However, signal steering vector is only known to lie subspace dimension greater than one. belongs linearly independent subspace. We propose two effective detectors according two-step design criteria generalized likelihood ratio test Wald test. It shown that proposed possess constant false alarm rate property have better performance their counterparts.
