Impact of MIMO Transmission on CAF-Based Geolocation
(Virginia Tech, 2013-08-27)
The Cross Ambiguity Function (CAF) is often used for passive geolocation of an emitter based on the time difference of arrival (TDOA) and frequency difference of arrival (FDOA) of the received signals. CAF performance has ...
Received Signal Strength-Based Localization of Non-Collaborative Emitters in the Presence of Correlated Shadowing
(Virginia Tech, 2013-05-23)
RSS-based localization is a promising solution for estimating the position of a non-collaborative emitter using a network of collaborative sensors. This paper examines RSS-based localization and differential RSS (DRSS) ...
Packaging of a High Power Density Point of Load Converter
(Virginia Tech, 2013-03-29)
Due to the power requirements for today\'s microprocessors, point of load converter packaging is becoming an important issue. Traditional thermal management techniques involved in removing heat from a printed circuit ...
Robust GM Wiener Filter in the Complex Domain
(Virginia Tech, 2013-01-28)
Space-Time Adaptive Processing is a signal processing technique that uses an adaptive array to help remove nonhomogeneous data points from a dataset. Since the early 1970s, STAP has been used in radar systems for their ...
A novel technique for phased array receivers based on an economic sampling scheme
(Virginia Tech, 2013-09-04)
Phased array systems present desirable antenna features like beam steering and high gain. However, due to their high cost, civilian applications cannot generally afford them, restricting their usage to military. Hardware ...
