False alarm measurements on receivers

An experimental approach to determining the false alarm rate of a receiver and the underlying theory are discussed. The approach proposed here is shown to be capable of generating quantitative false alarm rates of an EW receiver that are difficult to measure under normal operating conditions. It is shown that the predicted false alarm rate is very close to the measured data for sufficiently low values of the input noise ratio. This approach can reduce the measurement time and thus reduce the possibility of errors associated with long measurement times.
