Millimeter-wave radar sensor for automotive intelligent cruise control (ICC)

An all-weather automotive MMW radar sensor is described that uses an FMCW radar design capable of acquiring and tracking all obstacles in its field of view. Design tradeoffs are discussed and radar sensor test results are presented along with the applicability of the radar to collision warning systems.

Integrated automotive sensors

Focuses on automotive applications and discusses the development of a suite of integrated radar and IR sensors that can be used to surround a vehicle (car, truck, boat, etc.). The primary function is to provide information to the vehicle systems and operator as enhancements to passenger and vehicle safety. It may also provide vehicle information (speed, location, destination, etc.) and integrate information (weather, road/traffic conditions, service/rest-area location, route details, etc.) from an intelligent vehicle highway system.

Hinged, polarization diverse WLAN antenna

To fully realize the system potential of wireless local area networks (WLAN), polarization diverse antennas must be employed to minimize fading and optimize performance in dynamic, complex electromagnetic environments. An antenna solution that is integral to a WLAN PCMCIA card has been developed, demonstrated and the results presented here.

Photonically controlled wavelength division multiplexing (WDM) active array

Emerging missions for shipboard defense and tactical ballistic missile defense require the support of wideband, multi-function radars capable of concurrently performing hemispherical surveillance, tracking and simultaneous illumination of multiple targets. Active phased array antennas to support these missions are limited by their cost, bandwidth and aperture weight. As mission requirements become more demanding the integration of photonics into phased arrays, which promises increased bandwidth, decreased aperture weight and less complex transmit/receive modules, must be pursued. As part of the Office of Naval Researchs Accelerated Capabilities Initiative Raytheon, supported by the University of Connecticut, is developing a novel photonic antenna architecture for the control of active phased arrays. The photonic architecture is optically non- coherent and achieves a reduction in hardware complexity, and therefore array cost, via device sharing which is facilitated through wavelength division multiplexing (WDM). By properly configuring the photonic architecture, WDM represents a beneficial compromise between hardware complexity and array performance. To realize the photonic architecture the University of Connecticut is developing novel multiple quantum well photonic devices, including electronically tunable lasers and filters and a broadband amplitude modulator. This paper will discuss the antenna architecture wavelength division multiplexing and the enabling photonic devices.

Millimeter wave, solid-state amplifiers in radar and communication systems

Two different designs of millimeter wave, high-power, solid-state amplifiers are presented here, one each for use in missile radar and satellite communication applications. Details of each design are given along with the tradeoffs which led to the specific solid-state designs over other alternative solid-state and tube amplifier designs.
