A circuit for removing abrupt phase changes in a received signal, such as those caused when an object tracking system's directional receiving antenna becomes misaligned with the tracked object. The circuit uses a phase detector to determine when an abrupt phase change has occurred, such as when a signal...http://www.google.fr/patents/US4806934?utm_source=gb-gplus-shareBrevet US4806934 - Tracking circuit for following objects through antenna nulls
