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. In one embodiment, the scan strategy may be computed to operate in a manner cognizant of on-board active jammers, optimizing the jammer band and intercept band performance. The additional inputs for this task are a jammer band assignment table, and a blanking assignment table. The capability to generate "dry" (no jam) and "wet" (jamming) scan strategies for an emitter set is provided, with separate intercept rules for each.

What is claimed is: 1. A method for use in detecting emitter signals, the method comprising acts of: determining, for at least one emitter, a period at which a jamming signal is applied; determining, for the at least one emitter, a detection period, wherein the act of determining the detection period is based on the period in which the jamming signal is applied; and determining, for the at least one emitter, a revisit time based on a ratio between a minimum dwell duration among a plurality of emitters affected by the jamming signal and a minimum dwell duration of the at least one emitter. 2. The method according to claim 1, further comprising an act of limiting the ratio to a value of one. 3. The method according to claim 2, wherein the revisit time is scaled by the minimum dwell duration divided by the original dwell duration. 4. The method according to claim 1, further comprising an act of determining a dwell duration for the at least one emitter based on the determined revisit time. 5. A method for use in detecting emitter signals, the method comprising acts of: determining, for at least one emitter, a period at which a jamming signal is applied; determining, for the at least one emitter, a detection period, wherein the act of determining the detection period is based on the period in which the jamming signal is applied determining, for the at least one emitter, an indication that the at least one emitter is affected by the jamming signal; determining, for a receiving system, an indication that the receiving system is affected by the jamming signal; and comparing the indication that the at least one emitter is affected by the jamming signal and the indication that the receiving system is affected by the jamming signal to determine whether the at least one emitter is affected by the jamming signal. 6.
