The full text of this report is available for sale.During the above-noted period of this Final Technical Report, the following salient milestones were reached: (1) Introduced and demonstrated the concept of injecting electrons into the quantum dot (OD) active infra-red absorbing region from bracketing doped contact layers (to suppress unwanted dark current) leaving the QD region undoped; (2) Introduced and demonstrated the benefits of the concepts of (a) strain-relieving OD capping layers, (b) current blocking layers, and (c) lateral ...


Tracking Anti-Ship Missiles Using Radar and Infra-Red Search and Track: Track Error Performance JUN 2006
Authors:  Hwa-Tung Ong; DEFENCE SCIENCE AND TECHNOLOGY ORGANISATION EDINBURGH (AUSTRALIA)
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.The problem of association and fusion of radar and infra-red search and track (IRST) sensor reports is not straightforward, especially because IRST provides only angular measurements while radar provides range and range-rate measurements in addition to azimuth and elevation measurements. In this report, simulation results show that a centralised extended Kalman filter tracker is a solution that can capitalise on the higher angular accuracy of the IRST sensor to provide ...
