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; and

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.

2. The method according to claim 1, further comprising acts of determining a second method for detecting the signal, and determining at least one rule that defines how the receiver operates to detect signals from the source when configured according to the second method for detecting the signal.

3. The method according to claim 2, further comprising an act of determining, based on at least one of the at least one rule that defines how the receiver operates to detect signals from the source when configured according to the first method for detecting the signal and at least one rule that defines how the receiver operates to detect signals from the source when configured according to the second method for detecting the signal, which of the first and second detecting methods is used to detect the signal.

4. The method according to claim 2, further comprising an act of providing a user a capability to choose one of the first and second detecting methods to detect the signal.

5. The method according to claim 1, wherein the at least one rule indicates that the signal should not be observed, and wherein the method further comprises an act of evaluating whether the signal should be detected using the at least one rule.

6. The method according to claim 1, wherein the at least one rule indicates that the signal should be assigned default observation parameters that define how the signal is observed, and wherein the method further comprises an act of evaluating whether the signal should be detected using the at least one rule.

7. The method according to claim 1, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule, and wherein the method further comprises an 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.

8. The method according to claim 1, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule, and wherein the method further comprises an 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.

9. The method according to claim 1, further comprising an act of determining, for the first method for detecting the signal, a corresponding revisit time for observing the signal.

10. The method according to claim 2, comprising an act of determining, for the second method for detecting the signal, a corresponding revisit time for observing the signal.

13. 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; and

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.

14. The computer-readable medium according to claim 13, further comprising acts of determining a second method for detecting the signal, and determining at least one rule that defines how the receiver operates to detect signals from the source when configured according to the second method for detecting the signal.

The computer-readable medium according to claim 14, wherein the method further comprises an act of determining, based on at least one of the at least one rule that defines how the receiver operates to detect signals from the source when configured according to the first method for detecting the signal and at least one rule that defines how the receiver operates to detect signals from the source when configured according to the second method for detecting the signal, which of the first and second detecting methods is used to detect the signal.

16. The computer-readable medium according to claim 14, wherein the method further comprises an act of providing a user a capability to choose one of the first and second detecting methods to detect the signal.

17. The computer-readable medium according to claim 13, wherein the at least one rule indicates that the signal should not be observed, and wherein the method further comprises an act of evaluating whether the signal should be detected using the at least one rule.

18. The computer-readable medium according to claim 13, wherein the at least one rule indicates that the signal should be assigned default observation parameters that define how the signal is observed, and wherein the method further comprises an act of evaluating whether the signal should be detected using the at least one rule.

19. The computer-readable medium according to claim 13, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule, and wherein the method further comprises an 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.

20. The computer-readable medium according to claim 13, wherein the at least one rule indicates that at least one other rule should be evaluated with the at least one rule, and wherein the method further comprises an 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.
