FIELD: navigation instruments. SUBSTANCE: device has generator 1, radiator 2, receivers 3, 7, adjustable-delay unit 4, multipliers 5, 12, 14, integrators 6, 13, extreme- condition regulator 8, dividing units 9, 15, Hilbert transform unit 11, indicator 10, subtraction unit 16, squarers 17, 18; by searching for value of varying delay for minimum of ratio of results of product of cross- correlation function from delayed signal of first receiver and Hilbert transform of signal of second receiver with respect to cross-correlation function we proceed from delayed signal of first and second receiver signals to results of square differences of cross-correlation function, respectively. EFFECT: improved design. 1 dwg
