GDOP Effects in Multi-Static Radar

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.

A position error in my radar model is defined as the difference between the computed, estimated, or measured value and the true, specified, or theoretically correct value. Any measurement made or position estimated by a radar system there is an associated error. Here I aim to identify the errors associated with a multi-static radar system’s geometry, where they originate, and how to separate them from other system errors to create a model.

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.

Pulse Propagation Modeling in Dispersion Managed Optical Fibers

The following is an excerpt from a group project completed in my finial year at the University of Aberdeen. Dr. Kaliyaperumal Nakkeeran supervised the project. The group project title was Simulation of Pulse Propagation in Optical Fiber Transmission Systems. The aim of the project was to simulate the pulse propagation in dispersion managed (DM) optical fiber transmission systems. Effects like optical losses, group-velocity dispersion and self-phase modulation are analyzed in this project. Part of my contribution to the project was the production of a MATLAB simulation of the pulses’ propagation through the wave-guide.
