Abstract: A method for waveform-enabled jammer excision (WEJE) may include performing a jammer measurement during a look-through window when no signal-of-interest (SOI) is present and obtaining a jammer signal. A SOI-plus-jammer measurement may be performed and a SOI-plus-Jammer signal may be obtained when both the jammer signal and the SOI are present. Optimal weights that maximize a SOI-to-jammer power ratio may be determined. SOI-plus-jammer signals from a number of antenna elements may be optimally weighted and combined to copy the SOI and null the jammer signal based on the determined optimal weights.
