For the past 12 years the Canadian Department of National Defence and Raytheon Canada Limited have collaborated on a cost-shared programme to develop an Integrated Maritime Surveillance (IMS) system based on HF Surface Wave Radar (HFSWR). The primary objective behind the programme was to demonstrate the capability of HFSWR to continuously detect and track surface targets (ships and icebergs) as...

SIRTF requires detector arrays with extremely high sensitivity, limited only by the background irradiance. Especially critical is the near infrared spectral region around 3 μm, where the detector current due to the zodiacal background is a minimum. IRAC has two near infrared detector channels centered at 3.6 and 4.5 μm. We have developed InSb arrays for these channels that operate with dark cur...

Solid-state power amplifiers at W-band (75 110 GHz) are attractive for the generation of local-oscillator (LO) power for super-heterodyne receivers operating at sub-millimetre wave frequencies, as needed for example in future space instruments for Earth observation. Apart from space applications there is a growing interest for these devices in for example millimetre wave imaging, communication ...

In order to meet the requirements for future satellite applications, a brassboard of an extremely reliable fault-tolerant spaceborne computer (FTSC) has been developed by Raytheon Co., Sudbury, MA., under the sponsorship of the USAF/SAMSO. The requirements for the FTSC were high reliability, high speed, low power, high density and tolerance to space radiation environments. The reliability requi...

The defect containment measure is traditionally used to provide insight into project success (or lack thereof) at capturing defects early in the project life cycle, i.e., the time when defect repair costs are at their minimum. Although the measure does provide insight into the effectiveness of early defect capture techniques (such as peer reviews), defect containment in its most common form (pe...

Cleanroom is a set of software engineering principles that support the development of reliable software. The Systems group at Raytheon TI Systems, a SEI level 3 organization, successfully adopted Cleanroom into a pilot CMM level 5 project. The successful introduction of this technology was a result of the principles of Cleanroom being based on fundamental computer science foundations. As with a...

On Thursday 23 April 2015, several protests were held outside the gates of the Barclays Annual General Meeting at the Royal Festival Hall. Several activists bought shares and attended the AGM in order to ask questions. Anti-militarist activists held a protest calling on Barclays to divest from the arms trade. One activist read out an alternative chairman's speech to the queue of shareholders wa...

This paper presents preliminary results of a Raytheon project that uses systems dynamics to understand the intricacies of the U.S. educational system and to assist in exploring the effects of policies and programs, with a goal of doubling the numbers of science, technology, engineering and mathematics (STEM) college graduates by 2015. Specifically, a system dynamics model has been developed, th...

We apply speciication and veriication techniques based on the timed I/O automaton model of Lynch and Vaandrager to a case study in the area of automated transit. The case study models and veriies selected safety properties for automated Personal Rapid Transit (PRT) systems such as PRT 2000 TM , a system currently being developed at Raytheon. Due to their safety critical nature, PRT 2000 TM and ...
