Abstract :
In the paper, the effectiveness of two types of adaptive detectors of Gaussian coherent signals is compared against the background of Gaussian correlated interference - with coherent and non-coherent integration of output signals of an interference canceller. It is shown that at the maximum likelihood estimation of the adaptive canceller parameters, the detector with non-coherent integration can be not only simpler, but also more effective.
