This paper presents a performance analysis of likelihood ratio test (LRT)-based and generalized likelihood ratio test (GLRT)-based array receivers for the detection of a known signal corrupted by a potentially noncircular interference. Studying the distribution of the statistics associated with the LRT and GLRT, expressions of the probability of detection (PD) and false alarm (PFA) are given. In particular, an exact closed-form expression of PD and PFA are given for two LRT-based receivers and asymptotic (with respect to the data length) closed-form expression are given for PD and PFA for four GLRT-based receivers. Finally illustrative examples are presented in order to strengthen the obtained results.
