Abstract
In this paper, a scheme using Cross Ambiguity Function (CAF) map is proposed to estimate the location of an unknown interferer which emits harmful radio signal in the satellite communication network. In conventional CAF based TDOA, FDOA location, TDOA and FDOA are determined by location the peak in the CAF plane and then the peak’s information is fed into a least squares like location tool to determine the emitter’s location. However, this proposed scheme omits the step in which the location is determined with the post processed CAF peak information and instead maps the CAF surface directly to the earth surface. In simulation results, the distance error of about 800 m is occurred at Eb/N0 = 4–10 dB and the distance error of about 1.3 km is occurred at −20 dB of Eb/N0.
