Multiple Object Tracking in a Multi-Static Radar System

As part of my undergraduate degree at the University of Aberdeen, I completed an undergraduate thesis. In my thesis, I considered the concept of a multi-static passive radar system capable of tracking commercial civil aircraft using transmitters of opportunity.

One possible obstacle for a multi-static TDOA radar system is solving a system containing multiple targets. Solving the system quickly enough to enable a quick refresh rate, and real time operation is envisioned as a major obstacle as it could be prohibitive in terms of cost. In this entry I will discuss system complexity while tracking multiple targets, discuss the difference between real and ghost targets and approaches to reduce overall system complexity.

System Geometry and 2D Operation

This entry will detail the geometry of multi-static passive RADAR and describe how it obtains a target solution. For this report, a multi-static passive TDOA RADAR configuration will consist of a single receiving station that monitors for direct signals from the transmitters and indirect, multi-path signals reflected from potential targets. Other configurations are possible but the two-dimensional solution described here requires three transmitter-receiver combinations. To obtain a target the system measures the time difference of arrival (TDOA) of the multi-path signal is compared to the direct path signal from the same transmitter. Solutions for possible targets are calculated using the measured TDOA timings.

Multi-Static TDOA Radar

This entry will cover some of the basic principals of a passive radar system. Using an example system bellow the basic principles of a multi-static TDOA passive radar system will be explained. The basic outline provided in this post will be built upon in the future.

Passive radar overview

As part of the finial year of my degree at the University of Aberdeen, I completed an undergraduate thesis. In my thesis, I considered the concept of a multi-static passive radar system capable of tracking civil aircraft using transmitters of opportunity.

I aim to use this journal as a means of exploring the ideas outlined in my thesis and expand upon them. Using this journal I will break down my thesis and re-examine the background, principals, motivations, benefits and applications of a multi-static passive radar system.

This entry will discuss the motivations behind a civil aviation application for a passive radar system.
