Reels of fiber are generally used to test fiberoptic components and compare various network archetectures. It is possible in this fashion to measure the bit-error rate, power penalty and other characteristics of a nominal fiberoptic link within the confines of a laboratory.
However such measurements cannot easily be automated and practical considerations tend to limit the number of test cases. As a consequence stress testing, or pushing test conditions beyond the nominal case as well as the systematic measurement of design margins has not been widely available to designers of fiberoptic components and networks.
Optical fiber emulators which replace reels of fiber with advanced electro-optical modules to produce a controllable amount of signal degradation address many of these issues. The design of such emulators presents many challenges which are discussed in this paper along with specific test cases.
Pointing errors can compromise the performance of laser systems and cause numerous operational problems. In this paper, alignment tolerances for a bistatic sensor pod are derived from first principles. The method applies to a sizeable class of problems but is particularly relevant to military applications like laser target designation and rangefinding. It yields exact or conservative estimates in most cases of practical interest. Various results are explored from the point-of-view of employment methods and military deployment.
The Canadian Department of National Defence (DND) has established a requirement for a fleet of reconnaissance vehicles equipped with a modern surveillance system to be used in a wide variety of scenarios. This includes conventional operations within NATO, contingency operations in troubled areas as well as UN peacekeeping missions. As such, the Light Armored Vehicles Reconnaissance and Surveillance System will be the first 24 hour all- weather reconnaissance system integrated into a combat vehicle. This paper intends to describe how the operational requirements defined by DND were translated into sensor and system requirements. After a summary of the current configuration, it focuses on product pre-planned improvements and future needs.
