ABSTRACT:
A transmitter of a platform is arranged to generate a transmission pulse, which is transmitted to a receiver of another platform and is also arranged to couple its transmission pulse to a digital receiver associated with its platform via an attenuator and a coupler. Another platform performs a similar task. Each digital receiver determines the time separation between its transmission pulse and a received pulse from the other platform. The determined time separation information is shared with the other platform, and each digital receiver then determines a time offset between the time at its platform and the other platform.
