Ship Detection Using Inmarsat BGAN Signals

摘要

In this paper we present a bistatic passive maritime surveillance system based on the use of signals from Inmarsat I-4 satellite Broadband Global Area Network (BGAN) band. An experimental set-up is presented with a stationary passive receiver designed for acquisition and processing of Inmarsat signals. A description of signal processing aspects is provided, including the clutter cancellation, range-Doppler cross correlation, and experimental analysis of the ambiguity function. For the first time the detection and bistatic range-Doppler target location by reflected Inmarsat signals are presented for a typical maritime target.
