Processing design of a networked passive coherent location system

This paper outlines the design of a bistatic passive coherent location radar receiver system using Software Defined Radio (SDR) techniques. The receiver of the bistatic system is made up of a RF front-end, digitisation section, digital signal processing section and user interface. The integration of various components of the system are discussed. The digital signal processing stages of the system are implemented using general purpose computing hardware in an attempt to keep development costs to a minimum. The design is then elaborated to form a multi-static system which consists of several receiver nodes and multiple illuminators of opportunity.
