Predictive Mode

Sometimes it is desired to set total target delay less than the system minimum delay. While it is impossible to create a delay less than the minimum, under certain circumstances it might be possible to simulate this with predictive mode. Instead of trying to delay less than the system minimum delay, the RTG can store a radar pulse and use it to create a target for the next arriving radar pulse.

Predictive mode requires the following:

  • Pulse Invariant personality.
  • Pulse repetition interval (PRI) is fixed and known. It must be provided to the RTG through an API method.
  • The pulse must not change frequency or any other pulse characteristic.

For predictive mode to work, the RTG must make configuration changes relative to a radar pulse using either of the Relative to Pulse Rising Edge or Relative to Pulse Falling Edge. This is because changes need to be made at precise times in the PRI.
