The Development of the Invariant Algorithms of Coherent Accumulation of Useful Signals with Unknown Doppler Frequency
ABSTRACT
The optimal detection/estimation algorithms require large computing expenditures in the radar, sonar and etc. The paper presents the new Uniformly Most Powerful Test for matched detecting of the symmetrical signal subspace. The general (logical) shift operators group is used for describing of the symmetry. This algorithm may be used to reduce the complexity of matched detector for unknown signal subspace and for signal processing in real time. The reduction brings appreciable hardware gains and a small performance penalties in some interesting cases. We used the new methodology for creation of the sub-optimal detector for some symmetrical subspace signal model. The analytical expression for the detector performance loss is obtained by for some signal subspace.
