Russell K Johnson, James Alan Ivey, Yadunath Bhagvantrao Zambre: Waveform-enabled jammer excision (WEJE). LOCKHEED MARTIN CORPORATION, McDermott Will & Emery, July 18, 2017: US09712275

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 bo ...
