ABSTRACT:
The invention relates to a radar telemetry device.
The device comprises a first loop for the distance tracking of a moving echo comprising a detector for the position deviation of an echo signal and a telemetry mark, means for the digital calculation of the distance of the echo, means for generating clock pulses and means for generating a reference tracking window by the adding-subtracting of clock pulses. A second analog loop connecting the output of the add-subtract counting means to the deviation detector ensures a time filtering of the reference tracking window.
