Modification of the ESAMS Model to Include RWR False Alarms, Signal Dropouts, & Sensitivity
Abstract
In detecting threat radar signals via the penetrator aircraft's RWR, we need to be concerned about three crucial parameters: receiver false alarms and the ECM response to these false alarm signals, undetected threat signals (signal dropout), and receiver sensitivity. False alarms are those falsely detected signals in the absence of transmitted threat radar signals while signal dropouts are the absence of a detected signal in the presence of an actual transmitted threat radar signal. Receiver sensitivity defines the minimum signal strength a receiver can detect above the background noise density. These parameters are the most common anomalies in the reception of RF signals by the penetrator's RWR, hence EW simulation models such as ESAMS should be cognizant of these anomalies. Therefore these models should also incorporate a signal to noise power ratio, a false alarm probability, and receiver sensitivity variabilities into the model to simulate a more realistic engagement scenario.
