ABSTRACT:
The present invention provides a spread spectrum waveform encoded altimeter. Spread spectrum carrier wave signals which are transmitted and later received are processed in a novel edge detecting apparatus which includes a plurality of individual detectors. A pair of detectors are provided to detect an early chip or signal. Another pair of detectors are provided to detect a late chip or signal. There is also provided a pair of edge chip detectors for detecting the center or locked on chip signal. Logic circuits are employed to sum the voltage signals from the detectors and to provide a control signal capable of adjusting a tracking generator to enable it to lock on to the received signal. An altimeter counter is provided which is started by a unique chip in the transmitted signal and stopped when the same unique chip is detected in the receiving and tracking loop.
