Abstract

A system and method is provided for detecting emitter signals and for determining a scan strategy for a receiver system that receives such emitter signals. A rule-based system is provided for determining how emitters should be detected by a detection system. Rules may be used to prioritize certain emitters with respect to other emitters. The rules may also specify parameters for emitter modes, such as probability of intercept, turn-on range, detect-by range, tolerance, tolerance direction, scan periods, and other parameters. The rules may be used to compute the revisit time for the receiver. Multiple sets of rules may be created and a scan strategy may be computed based upon the selected rule set.

Claims

1. A method for detecting a signal from a source, using a receiver, the method comprising acts of:

determining a first method for detecting the signal;

determining at least one rule that defines how the receiver operates to detect signals from the source when the receiver is configured according to the first method for detecting the signal, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule; and

selecting one of the at least one rule and the at least one other rule having the most difficult solution to detect the signal, wherein the act of selecting one of the at least one rule and the at least one other rule having the most difficult solution to detect the signal includes an act of determining a corresponding revisit time associated with each of the first method and second method for detecting the signal, and selecting the method having a lesser value of revisit time.

2. A method for detecting a signal from a source, using a receiver, the method comprising acts of:

determining a first method for detecting the signal;

determining at least one rule that defines how the receiver operates to detect signals from the source when the receiver is configured according to the first method for detecting the signal, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule; and

selecting one of the at least one rule and the at least one other rule having the least difficult solution to detect the signal, wherein the act of selecting one of the at least one rule and the at least one other rule having the least difficult solution to detect the signal includes an act of determining a corresponding revisit time associated with each of the first method and second method for detecting the signal, and selecting the method having a lesser value of revisit time.

3. A computer-readable medium having instructions stored thereon that, as a result of being executed by a computer, instruct the computer to perform a method for detecting a signal from a source, using a receiver, the method comprising acts of:

determining a first method for detecting the signal;

determining at least one rule that defines how the receiver operates to detect signals from the source when the receiver is configured according to the first method for detecting the signal, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule; and

selecting one of the at least one rule and the at least one other rule having the most difficult solution to detect the signal, wherein the act of selecting one of the at least one rule and the at least one other rule having the most difficult solution to detect the signal includes an act of determining a corresponding revisit time associated with each of the first method and second method for detecting the signal, and selecting a method having a lesser value of revisit time.

4. A computer-readable medium having instructions stored thereon that, as a result of being executed by a computer, instruct the computer to perform a method for detecting a signal from a source, using a receiver, the method comprising acts of:

determining a first method for detecting the signal;

determining at least one rule that defines how the receiver operates to detect signals from the source when the receiver is configured according to the first method for detecting the signal, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule; and

selecting one of the at least one rule and the at least one other rule having the least difficult solution to detect the signal, wherein the act of selecting one of the at least one rule and the at least one other rule having the least difficult solution to detect the signal includes an act of determining a corresponding revisit time associated with each of the first method and second method for detecting the signal, and selecting a method having a lesser value of revisit time.
