Abstract

In this paper the practical feasibility of a mixed WiFi transmissions based passive bistatic radar (PBR) is analyzed. The required data processing steps are described with reference to mixed DSSS and OFDM transmissions for both: (i) the control of the signal Ambiguity Function usually yielding a high sidelobe level and (ii) the removal of the undesired signal contributions which strongly limit the useful dynamic range. The performance of the conceived system is evaluated with reference to typical signals broadcasted by a IEEE 802.11 access point. This allowed us to demonstrate the potentialities of a WiFi-based PBR for local area surveillance applications.
