In late June this year, the US Department of Defense (DoD) announced that fatalities from roadside bomb attacks in Iraq had dropped by nearly 90 percent over the previous year. In May of this year, improvised explosive devices (IED) claimed the lives of 11 US troops. Compared to the...

This article briefly outlines the research and development activities in radar absorbing materials. First, the structure and working mechanism of traditional radar absorbing architectures such as the Salisbury screen and the adaptive radar absorber are introduced. Second, the major breakthroughs, including the successful fabrication of dynamically radar absorbing materials,...

Modern radars using frequency chirp modulation present many measurement challenges to the designer and system engineer. Complex test systems involving many instruments have traditionally been required to validate radar performance. Automatic measurements in a single instrument can be the key to simplifying radar test and improving test reproducibility. This...

Many forms of data transmission utilize various forms of Automatic Repeat reQuest (ARQ), where data which has not been received or correctly decoded is automatically requested. This guarantees delivery of the full packet of data, for instance to make sure that the whole web page is displayed. When data...

I. INTRODUCTION The availability of low-cost, high performance amplifiers is crucial to the continued development of mm-wave commercial applications from 17 to 40 GHz. Typical applications include wireless data links such as Local Multipoint Distribution Service (LMDS) and point-to-point microwave radio as well as automotive 24GHz, instrumentation, and VSAT...

1. INTRODUCTION CDMA (IS-95) has a multiple access scheme based on spread spectrum technology, which has been applied to digital cellular mobile communications since the early 1990s. The number of traffic channels used depends on the number of users in the cell. Thus the output signal of the IS-95...
