Optimal algorithms of band-limited noise signal detection are synthesized. The decision on the presence or absence of a signal is taken from the result of likelihood functions comparison. The block diagrams of optimal and quasi-optimal detectors are developed. The analytical expressions of probabilistic and power characteristics for different ratios of useful and noise signals are obtained. Curves...
Algorithms and block diagrams of signal processing in the Dicke-type radiometer are synthesized on the basis of the theory of optimal statistical decisions and parameters estimates of probabilistic distributions. Limit errors of required parameters estimates in the received optimal algorithms and potential fluctuation sensitivity of the developed block diagrams are investigated.
The optimal algorithm of multiband spatio-temporal radiometric signal processing is synthesized. Analytical expressions both for the potential fluctuation sensitivity of the system designed according to the algorithm and for the ambiguity function of multiband radiometric systems are deduced. An example of the theory application is demonstrated.
