FIELD: measurement engineering. ^ SUBSTANCE: device has sync pulse oscillator, transmitter, aerial unit, receiver, selected automatic amplification regulator, reflected pulses auto-tracking system which has time modulator, time dicriminator and integrator, capture system and processor unit, which forms output data in specified form. The following units are introduced into device additionally: reference signal controlled reflector, transmitter starting delay unit, probing pulses repetition frequency normalizer, AND and OR gates, which close the circuit for re-circulation of selector pulses of time modulator in mode of reflected pulses tracking, logic valve, which passes delector pulses through to inputs of time discriminator and of selected automatic amplification regulator only during periods of re-circulation, into which periods the transmitter is started. ^ EFFECT: improved precision of measurement of altitude; widened functions of processor unit. ^ 3 dwg |
