The objective is the development of a high power microwave antenna to operate with 100 megawatts pulsed input at L band. Unfortunately, the present dish antennas capable of achieving this objective are too large for use on Army land vehicles (HMM) and airplatforms (Blackhawk). With recent antennas in dielectric materials, forrelectric materials, semiconductors, and plasmas, coupled with advances ...

Astron proposes to develop and demonstrate a series of compact, extremely high power transmit/receive anennas to cover (with a minimum number of antenna elements) the HF through UHF frequency range. These antennas are intended for on-the-move operationsin airborne and also vehicular applications. Antenna miniaturization and broadbanding are stressed.

This SBIR is concerned with the operational use of acoustic sensors mounted on an operating vehicle to detect and localize targets, including other vehicles, in the surrounding environment. In general, several classes of noise limit the performance ofthese types of acoustic systems. Two key classes are the near field noise generated by the platform itself and the far field noise generated by inter ...

A nearly universal trend in modern technology is the continued integration of systems, and their associated devices, on decreasingly smaller scales. While this has led to personal computers that offer more functionality and faster computational speeds, ithas also spurred the development of hybrid optoelectronic systems on a chip (SOCs). Currently, such SOCs are receiving significant interest fro ...

Blast parameter measurement is imperative to improve and verify current theoretical predictions of new weapon effectiveness and structural responses to blasts. A number of variables such as fuse initiation, explosive charge shape, charge burn rate, andambient conditions determine blast wave characteristics and complicate theoretical predictions. Experimental verification of theoretical models is d ...

Application extensibility and personalization, flexible querying of databases, schema (dictionary) integration, and automatic data translation are significant problems for the interoperation and integration of distributed systems. We seek an innovativesolution to these problems through the development of a semantic mapping and modeling toolkit, which we refer to as userSMARTs(tm), and a companion ...

Global competition coupled with the fast changing moods of the customer base has led commercial automotive manufacturers to increase the speed at which they can change and bring new attractive products to market. All of these products face long termcorrosion warranties and this information is normally derived by conducting accelerated corrosion tests on selected vehicles prior to release for comme ...

Rapidly assessing fuel quality represents a significant challenge for the Department of Defense both in the field and in storage/distribution facilities. The ability to monitor fuel quality on site and in real time would offer significant advantages overcurrent laboratory testing methods. It has been demonstrated that vibrational spectroscopy is capable of correlating the chemical information con ...

Communication and wireless network technology has advanced to the state whereportable computing devices have proliferated to enable ubiquitous computing.Similarly, Internet and collaboration technologies have grown tremendously. Thereremain significant obstacles, however, to integrate wireless and Internettechnologies. In particular, most modern wireless networks do not provide adequatesupport fo ...
