ALTITUDE RADIOSENSOR Russian patent published in 2008 - IPC G01S13/93 

FIELD: physics, radio.

SUBSTANCE: suggested invention is related to radio location equipment, namely, to altitude radiosensors, and may be used for generation of preset altitude passage signal by descending object. Units are introduced that make it possible to delay gate pulse in relation to emitted pulse with high accuracy. Altitude radiosensor contains synchroniser, modulator, transmitter with pulse modulation, the first and the second generators of delayed gate pulses, pulse distributor, the first and the second integrating circuits, differential amplifier and receiver, timer, transmitting-receiving antenna, isolating unit, the first and the second directional couplers, the first and the second superhigh frequency switches and device for delay of superhigh frequency signal that are connected to each other in a certain manner.

EFFECT: higher accuracy of preset altitude passage signal generation by descending object.
