Beschreibung
Zusammenfassung:	FIELD: radio engineering. SUBSTANCE: given radio altimeter is intended for precision establishment of flight altitude of artificial earth satellite, parameters of gravitational field, determination of shape of geoid, land relief, topography of ice fields and ocean, specifically, height of inequalities of underlying surface and oceanic waves. Radio altimeter includes generator of linear frequency modulation pulses, former of sounding and heterodyne signals, amplifier, decoupling unit, antenna, two mixers, receiver, range search unit, unit for synchronization and formation of time substitutes, digital adder, band-pass filter, three squarers, seven low-pass filter, attenuator, three subtracters, adder, retunable heterodyne, averaging counter, two amplitude detectors, integrator, inverter, two retunable band-pass filters, phase detector, analog-to-digital converter. EFFECT: required unambiguity zone o measurement without loss of precision in real time. 4 dwg
