Abstract
Many literatures regarding the coexisting radar and communications assume that some information is exchanged mutually, i.e., they work in a cooperative or coordinated manner. In this letter, we consider an uncoordinated scenario to examine the influence of the unknown communication interference on the active radar target detection, just provided with a known power of the transmitted communication signal. To this end, a numerical generalized likelihood ratio test (GLRT) in the partially homogeneous clutter is derived to handle this problem, with the maximum likelihood estimations (MLEs) approximately solved. Simulations illustrate the superiority of the addressed detector, principally in the strong interference environment.
