In this entry I will describe the geometry of multi-static passive radar and how it obtains a target solution. The multi-static passive TDOA radar example in this entry consists of a single receiving station that monitors the direct signals from the transmitters and indirect, multi-path signals from potential targets. Other configurations are possible but the 2D operation described requires 3 transmitter – receiver combinations. To obtain a target the system uses the time difference of arrival (TDOA) of the multi-path signal compared to the direct path signal from the same transmitter. Using these timings, solutions for possible target locations can be generated. I will cover the basic bi-static geometry on which this system relies and how it is incorporated into multi-static system. A 2D solution will also be derived from scratch for a multi-static system.

Wednesday, December 31st, 2008This 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.

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 multistatic 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 multistatic passive radar system.
