Abstract
A traffic radar system utilizes a standard USB interface of power and communication to a host USB device. Modules of the radar system communicate over a wireless network to reduce hard-wire cabling in the patrol vehicle or radar platform. Digital signal processing (DSP) is utilized in a distributed processing architecture to increase processing functionality and target detection capabilities. The system modules incorporate electrical and mechanical interfaces which allow modules to be connected together to form unique radar systems.
