METHOD OF MEASUREMENT OF RADAR REFLECTION CAPACITY Russian patent published in 1995 - IPC

FIELD: radiolocation. SUBSTANCE: device for realization of method includes generator 1 of reference signal, synchronizer 2, first 3, second 4 and third 5 delay lines, valve 6, first 7, second and third 9 directional couplers, comparator 10, controlled attenuator 11, antenna switch 12, mixer 13, heterodyne 14, intermediate frequency amplifier 15, line detector 16, first 17 and second 18 keys, first 19, second 20, third 21, fourth 22, fifth 23 and sixth 24 integrators, pulse generator 25, antenna 26, gating unit 27, square-law detector 28, first 29, second 30, third 31 and fourth 32 subtracters, squarer 33, first 34 and second 35 multipliers, first 36, second 37 and third 38 adders, antilogarithm taking unit 39 and counter 40. Increased precision of measurement of radar reflection capacity is obtained thanks to correction of errors caused by difference of distributions of intensities of echoes, by logarithmic conversion of these distributions and actually by repeat logarithmic conversion of calibration signal. EFFECT: increased precision of measurements of radar reflection capacity. 1 dwg
