Radar has been used for observation of weather since the 1940s. 1 Advances in weather radar include the incorporation of Doppler capability, which allows measurement of wind velocity, and the use of multiple polarizations, which enhance rainfall estimation and provide the ability to discriminate between types of hydrometeors, such...

Due to the fast development of wireless communications, a low cost, high performance, high integration technology is needed for system on a chip (SOC) implementation. The CMOS technology provides a good solution for SOC integration. 1 Recent improvements of the standard CMOS process make it possible to implement RF...

The number of mobile users is predicted to reach 1.7 billion by the year 2010. More than 45 percent of them will use high data speed services. W-CDMA, proposed by IMT2000, has become the most practical and important system for the development of new wireless communications. Nevertheless, second generation...

From mobile telephones to wireless Internet access to networked appliances and peripherals, there is an increasing reliance on wireless communications to provide or enhance functionality for products and services. The wireless communications industry continues to generate new products and applications for consumers and new opportunities for businesses. The enormity...

Successful microwave circuit realization requires flexible circuit analysis tools that allow engineers to prototype, analyze and verify their circuits. Today, available software tools offer standard features such as frequency analysis, tuning and optimization, but are differentiated by their model libraries and special customization capabilities. This article describes the design...

Raytheon Co. delivered the first production Evolved SEASPARROW Missile (ESSM) to the US Navy, defining the future of ship defense. "ESSM provides improved ship self-defense capabilities against faster, lower, smaller and more maneuverable anti-ship missile threats as well as increased firepower," said Capt. Ken Graber, the NATO SEASPARROW project...

Air Force Security Forces personnel supporting Operation Enduring Freedom have been equipped with the latest in Unmanned Aerial Vehicle (UAV) technology, the Force Protection Airborne Surveillance System (FPASS). The system allows security forces to see beyond base perimeters and can provide a rapid visual assessment of detected threats. The...

Loral Space and Communications announced that the US Navy's Space and Naval Warfare Systems Command (SPAWAR) has awarded a Space Systems/ Loral (SS/L) team, led by Raytheon, a $40 M Component Advanced Development (CAD) contract to develop the US Navy's $6 B, next-generation, satellite-based mobile communications system, the Mobile...

BAE Systems successfully launched a 2.75" laser guided rocket using a unique mid-body, fin-mounted, guidance system, scoring a "bull's-eye" hit on a small target more than three miles away from its launch point. The control test vehicle (CTV) was fired Sept. 29 at the Army's Yuma Proving Ground in...

UK contractor BAE Systems Command, Control, Communications, Computing, Intelligence, Surveillance and Reconnaissance (C4ISR) has delivered the first batch of six Talon satellite communications terminals to Paradigm Secure Communications for eventual use in the UK's Skynet 5 military communications satellite system. In all, 15 such terminals will be acquired, with...
