FIELD: radar and radio navigation; data processing.SUBSTANCE: method comprises using a first sequence of pulses with repetition rate F, in which repetition period Tis several times smaller than base period T, selected from condition of unambiguous measurement of distance within entire possible range of distances to observed meteorological objects (MO), radiating in next interval Ta second sequence of pulses with repetition rate F, where F=zFand F=zF, where F=1/T; values zand zare not multiples of each other and have no common denominator, determining a set of observed delays t, where; I is total number of observed delays reflected from MO pulses relative to each k-th,; K is number of pulses emitted in first packet, emitted pulse in their first packet, calculation of average observed delay tof reflected pulses from MO relative to each of emitted k-th pulse in their first packet, determining a set of observed delays t, where; J is total number of observed delays of pulses reflected from MO relative to each p-th,; P is number of pulses emitted in a second packet, emitted pulse in their second packet, calculation of average observed delay of reflected pulses from MO trelative to each of emitted p-th pulse in their second packet, comparison of time delay t=mT+tand t=nT+t, where m and n are numbers of whole periods Tand T, falling within interval of true delay t, variation of numerical values of m and n until condition t=tis met with fixation, at which said condition is met, and calculating range to MO by formula D=c(mT+t)/2 or D=c(nT+t)/2, where c is speed of light.EFFECT: unambiguous measurement of distance to MO.1 cl, 2 dwg |
