Abstract

Interference of satellite communications is a frequent and ongoing concern for both DoD and civilian enterprises. Geolocation of the interfering source is an essential step in mitigating or eliminating the interference and restoring the operation of the communications service. Doppler information is useful for the passive geolocation of ground-based EMI sources. This paper proposes a cross-correlation-based method to blindly estimate the EMI Doppler information from a single satellite. In the proposed blind estimation method, the carrier and waveforms of the EMI sources are relaxed. Simulated numerical results demonstrate the effectiveness and accuracy of cross-correlation-based blind Doppler estimation
