Multistatic radar micro-Doppler

Abstract

This chapter reviews how multistatic radar sensor networks can be utilised to sense a series of different moving targets to extract their micro-Doppler (μD) signatures and use these for classification purposes. The field of radar has advanced significantly since its inception in the early twentieth century. From these origins, typical radar systems have evolved from single transmit/receive configurations into complex sensor networks characterised by a multiple nodal dynamic. The future of radar sensing is moving towards intelligent distributed sensing due to the many advantages this brings. There are still significant challenges that need to be addressed through innovative solutions, such as location and synchronisation even within a GNSS-denied environment, but promising solutions are already maturing in Technology Readiness Level (TRL).
