9 . The system of claim 8 , wherein in response to the on-board tracking signal being greater than or equal to the on-board tracking signal threshold, determine the navigation to the target object based at least in part on 1) the on-board tracking signal or 2) the on-board tracking signal and the scatter energy.

10 . The system of claim 9 , wherein in response to the on-board tracking signal not being greater than or equal to the on-board tracking signal threshold, determine the navigation to the target object based at least in part on 1) the scatter energy or 2) the scatter energy and the indication from the tracking station.

11 . The system of claim 8 , wherein the processor is further configured to determine whether the range is less than or equal to a closing range.

12 . The system of claim 11 , wherein in response to determining that the range is not less than or equal to the closing range, navigation is determined based on 1) the scatter energy or 2) the scatter energy and the indication from the tracking station.

13 . The system of claim 12 , wherein it is not determined whether on-board tracking signal is is greater than or equal to an on-board tracking signal threshold.

14 . The system of claim 11 , wherein in response to determining that the range is less than or equal to the closing range, it is determined whether on-board tracking signal is greater than or equal to an on-board tracking signal threshold.

15 . The system of claim 8 , wherein in response to the on-board tracking signal being greater than or equal to the on-board tracking signal threshold, it is determined whether an active measure is to be performed.

16 . The system of claim 15 , wherein in response to determining that the active measure is to be performed, the active measure is performed.

17 . The system of claim 16 , wherein in response to determining that the active measure is to be performed, it is determined whether the process is done.

18 . The system of claim 15 , wherein in response to determining that the active measure is not to be performed, it is determined whether the on-board tracking signal is greater than or equal to the on-board tracking signal threshold.

19 . A method, comprising:

receiving an indication, using a receiver, to intercept a target object from a tracking station;

determining, using a processor, navigation to the target object based at least in part on the indication;

determining whether a scatter energy is greater than or equal to a scatter threshold; and

in response to the scatter energy being greater than or equal to the scatter threshold, determining the navigation to the target object based at least in part on 1) the scatter energy or 2) the scatter energy and the indication from the tracking station.
