ALTIMETER Russian patent published in 2013 - IPC G01S13/93 

FIELD: radio engineering, communication.

SUBSTANCE: result is achieved owing to use of a serial delay line unit, a parallel coincidence element unit, read-only memory for a parallel delay line unit and an adder, wherein the output of the range converter is connected to the input of the serial delay line unit, having a group of outputs which is connected to a group of inputs of the parallel coincidence element unit, the input of which is connected to the output of the receiver, and the group of outputs is connected through the read-only memory to the first group of inputs of the adder, having a second group of inputs connected through the parallel delay line unit to the group of outputs of the range converter and a group of outputs connecting with a group of inputs of the indicator.

EFFECT: high accuracy of measuring altitude.
