Application of wide Band Receiver Architectures to Pulse Repetition Interval (PRI) Specific Emitter Identification (SEID)

Specific Emitter Identification (SEID) systems have been implemented using narrow hand receivers with fine grained Pulse Repetition Interval (PRI) analysis. The analysis produces a PRI signature on an emitter such that the same emitter is uniquely distinguished from another of the same type, allowing a user to associate an emitter to a specific platform. Using a narrow band tuner for this analysis isolates the emitter of interest from other signals in the environment ans allows it to be porcessed individually. This step reduces the burden of existing processors so that detailed analysis can be performed. Current state-of-the-art processing and wide band architectures may allow that one or more emitters of interest be analyzed for SEID date at the same time. The analysis may also be performed by processors already tasked to provide other ESM functions. This capability, if added to existing wide band threat warning systems, would strenthen the ESM posture of the host platform without adding any weight, power, size, or additional recurring hardware cost to the platform. The objective is to determine the utility of a wide band radar receiver architecture in performing SEID functions.
