The cross-correlation function of the incoming signal disturbed by EWF distortion and the locally-generated code signal is obtained analytically for threat models TM-A, TM-B and TM-C. These results are useful to evaluate efficiently the performance of EWF detectors, namely the detectability and hazard regions.engEvil waveformThreat modelThreat spaceconference object10.1109/NAVITEC53682.2022.98475532325-5455
