1. A computer-implemented method for tracking a target, said method implemented using a direction finding (DF) device and a control module, said method comprising:

  • receiving, at the DF device, a first signal associated with a first user device;

    transmitting, by the DF device, a DF device signal to the control module, wherein the DF device signal is associated with the first signal;

    receiving, at the control module, the DF device signal;

    receiving, at the control module, a second signal associated with a second user device, wherein neither the first user device nor the second user device are predefined as either an active target or an active tracking device;

    identifying, at the control module, the first user device as an active target when one or more characteristics of the first signal matches a first selection criteria in a predefined rule set;

    identifying, at the control module, the second user device as an active tracking device when one or more characteristics of the second signal matches a second selection criteria in the predefined rule set and;

    determining, by the control module, positional data associated with the first user device based on at least one of the first signal, the second signal, and the DF device signal.
