Abstract
GSM based passive radars employ the GSM signal transmitted by GSM base stations as an illuminator. A model of GSM signal, called Multi-Burst Mapping Model (MBMM), which can be convenient to depict the GSM signal data stream, is presented. The mapping structures of multi-burst GSM signal are constructed, and the mapping method is offered. With it, the multi-burst GSM signal data stream can be obtained. In a burst, the whole GMSK modeling phase is generated by compound method, thus GSM signal can be simulated. In addition, many of GSM signal ambiguity functions are observed and a feature of them is found: while the length of data is long enough (more than one frame), they belong to thumbtack functions. This feature is investigated in many aspects and validated via Monte Carlo method.
