FIELD: physics.
SUBSTANCE: searcher contains a multiplier, frequency operated generator, pre-adder, accumulated sum converter, multichannel correlator, two delay elements, three RAMs, two quadrature filters, maximum determinant, feedback adder, stack for "К" positions and resolver. Multichannel correlator contains interleaver, range code generator and memory. Quadrature filters contain adders, envelope computer, and maximum determinant. The searcher can be used in navigation signal receivers, such as GPS, GLONASS, Galileo.
EFFECT: decreased total time of signal search.
