METHOD AND APPARATUS FOR IDENTIFYING OWNSHIP THREATS
First Claim
1. A threat evaluation system comprising:
- a receiver associated with an object, the receiver adapted to implement a scan strategy including a dwell arrangement to receive signals emitted by one or more threat emitters, the signals being emitted by the one or more threat emitters to locate the object or similar items; and
a tracking system that receives information from the receiver regarding received signals, the tracking system analyzing signals from a threat emitter to provide a track indication that the threat emitter is actively tracking the object without adjusting the dwell arrangement of the scan strategy of the receiver.

Abstract
A method and apparatus for evaluating whether one or more threat sources is actively tracking an object, such as an aircraft. A tracking system may analyze information regarding signals received from a source and provide a track indication that the source is actively tracking the object without adjusting the dwell arrangement of the scan strategy of the receiver. A track indication may be provided where a sample count of signal intercepts from the source is greater than a track count during a window. A break track indication representing that the source is not actively tracking the object may be provided when a number of signal intercepts from the source is less than a break track count during a window.

10. A threat evaluation system comprising:
-
a receiver associated with an object, the receiver adapted to receive signals emitted by one or more threat emitters, and providing an indication of at least one signal intercept from a threat emitter based on one or more signals received from the threat emitters the signals being emitted by the one or more threat emitters to locate the object or similar items; and
a tracking system that receives information from the receiver regarding signal intercepts, the tracking system analyzing at least one signal intercept from the threat emitter and providing a track indication that the threat emitter is actively tracking the object when a sample count of signal intercepts from the threat emitter is greater than a track count during a window, and providing a break track indication that the threat emitter is not actively tracking the object. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of identifying one or more threats to an object, comprising:
-
implementing a scan strategy for a receiver, the scan strategy including a dwell arrangement defining one or more time periods during which the receiver is intended to receive signals from one or more directions;
receiving, at the receiver, signals emitted by one or more threat emitters, the signals being emitted by the one or more threat emitters to locate an object associated with the receiver; and
providing, based on the received signals, a track indication that at least one threat emitter is actively tracking the object without adjusting the dwell arrangement of the scan strategy for the receiver.
