FIELD: radio engineering, communication.SUBSTANCE: range-finder comprises a first delay line connected to an adder with a positive and a negative summation weight, series-connected zero detector and coincidence circuit, as well as a second delay line. The range-finder also includes a comparator circuit, inputs of which are connected to the outermost leads of the second delay line and the output is connected to the second input of the coincidence circuit, wherein the output of the adder is connected to the input of the second delay line and the middle lead thereof is connected to the input of the zero detector.EFFECT: eliminating false readings when measuring range.1 dwg |
