To realize next generation missile defense radar systems with a significant improvement in performance requires more cost effective system implementations. Software defined radar (SDR) technologies together with field programmable gate array (FPGA) implementations promise reusable and low cost DREX multichannel receivers in smaller form factors. Real time firmware reconfiguration enables radar mod ...

In order to maintain our nation’s technological superiority on air, sea and land, we must respond quicker to emerging threats and reduce the cost of major sensing platforms. Every DoD platform developed nowadays contains at least one sensor, whether it be RF, EO/IR, or acoustic. In fact, in a lot of recent developments, the platform is built around the sensor and exists only to support the senso ...

A multi-band airborne synthetic aperture radar and ground moving-target indicating (SAR/GMTI) radar system will be designed and developed that will utilize multiple frequency bands to improve the radar imaging and target detection performance in various clutter environments. Applied Radar’s existing wideband digital receiver/exciter (DREX) hardware is inherently capable of supporting radar appli ...

Multi-channel array manifolds are required for wideband AESA applications. In modern solid-state AESA arrays, MMIC-based T/R modules generally utilize digitally-controlled phased shifters to steer the beam on transmit and receive. The given phase value is only accurate at one frequency, and so for wide bandwidths of several hundred MHz (at X-band for example), the beam does not get formed properly ...

Key obstacles to extending OFDM to wireless links and networks at high-frequencies and dynamic channels are inherent low performance to Doppler and power amplifiers operation with high back-off. Other significant obstacles are multipath and impulsive noise. PEARL-OFDM combines a layered architecture with technologies that mitigate such obstacles and enable full-range rates that maximizes connectiv ...

This proposal details the development of a new FCG design that reduces energy losses for small package sizes. It addresses the major performance limiting factors associated with small helical FCGs and facilitates driving high output voltage, moderate current loads directly, without the need for a transformer. Applications for this device include single shot, high peak power loads for directed en ...

We propose the development of a compact broadband underwater cylindrical transducers with integrated tuning networks and power amplifiers for Mobile Acoustic Counter Measures. There is a need for cost effective transducers that are broadband and have broad-beam coverage. BTech has designed and built improved counter measure transducers as well as acoustic modem transducers using both PZT materials ...

The design and development of piezocrystal sonar transducers is a challenging multidisciplinary and technological effort that spans many fields and skill sets. We look to extend and improve our transducer assembly technologies to reduce cost and implementation time for sonar technology transition and in particular our methods for Active-Passive single crystal ring development and fiber glass wrapp ...

Application of agrochemicals is essential to U.S. production of food, fiber, biofuels and ornamentals. However, it can also create environmental contamination if pesticides reach non-target areas through airborne displacement of spray, i.e., "spray drift". Drift is a concern for agriculture, especially for specialty crops grown in sensitive areas. Spray drift mitigation, through use of larger drop ...

DESCRIPTION (provided by applicant): The purpose of this fast-track SBIR project entitled Paragraph and Essay Writing Instruction for Struggling Secondary Writers is to develop and evaluate the effectiveness of a total of four interactive multimedia (IM) software programs to be used to teach complex writing skills to struggling writers in secondary schools. The foci of the four programs will be ...
