Detection of Stochastic Signals in Passive MSRSs in a Background of Spatially Uncorrelated Interferences

As was mentioned in Section 4.1, detection of stochastic signals is the task of passive MSRSs (or active–passive MSRSs in a passive mode) which receive signals from sources of “noise” radiation. The assumption that a correlation matrix of stochastic signals is completely known (deterministic correlation matrix) is a methodically convenient idealization similar to the assumption of the deterministic character of regular signals (Sections 4.1,5.1).
