Implementation of Passive Radar with a Software Defined Radio Platform

Departments: Electrical and Computer Engineering
Advisor: Rick Blum

Abstract:
Passive radar is a bistatic radar which does not require a transmitter. It utilizes the reflected energy of electromagnetic waves in the environment from third-party sources to detect and track targets. Passive radar is advantageous to traditional radar systems as it is usually much more cost effective, can be used for covert operations, and is difficult to jam. Software Defined Radio (SDR) is a radio system comprised of wideband, software independent hardware with signal processing executed on a general purpose processor. SDR can be used to explore a wide band of frequencies allowing multiple bands to be utilized and allowing cognitive capabilities such as those seen in cognitive radio. This research focuses on the implementation of a passive radar on SDR platforms. Simulations and signal processing have been accomplished with various software packages such as GNURadio and Matlab. SDR platforms such as the RTL2838 chipset and USRP have been used to identify real signals and reflections. This research can prove the feasibility of implementing passive radar on SDR platforms, expanding the capabilities of current passive radar technologies.
