*** 96-61180 Djuth This Small Business Innovation Research (SBIR) Phase I project will develop solid state transmit/receive modules that are optimized for remote sensing of the Earth's atmosphere, ionosphere, and magnetosphere. Such units would pave the way for a new generation of UHF phased array radar having greatly improved system performance and flexibility. Projected system costs are significantly less than those of traditional radar. Phase I will develop a new solid-state power amplifier, complementary antenna design, and an improved low-temperature transmit/receive switch. A shift away from high-power tube amplifiers to distributed solid-state units will be examined. The new radar can be configured for rapid tracking of dynamic geophysical events from the zenith to low elevation angles. Because the system architecture is modular, it is well-suited for radar interferometry and can be incrementally expanded to sizes characteristic of a powerful incoherent scatter radar. A very high sensitivity radar would require 4000-5000 modules. Potential commercial applications include incoherent scatter radar development, radar tracking and imaging of airborne "hard targets," meteorological aids, radar wind profiling in the stratosphere and troposphere, high-power ground penetrating radars (for hydrological studies, detection of hazardous waste, oil/gas reserves), pagers, cellular telephone systems, and military communications. ***

*** 96-61180 Djuth这项小型企业创新研究（SBIR）I期项目将开发固态发射/接收模块，这些模块已针对地球大气，电离层和磁层进行了优化。 这样的单元将为新一代的UHF分阶段阵列雷达铺平道路，具有大大提高的系统性能和灵活性。 预计的系统成本大大低于传统雷达的成本。 第一阶段将开发新的固态功率放大器，互补天线设计，并改善了低温发射/接收开关。 将检查从高功率管放大器转移到分布的固态单元。 可以配置新的雷达，以快速跟踪从天顶到低海拔角度的动态地球物理事件。 由于系统体系结构是模块化的，因此它非常适合雷达干涉法，并且可以逐步扩展为强大的不连贯散点雷达的大小。 非常高灵敏度雷达需要4000-5000个模块。 潜在的商业应用包括空降“硬目标”，气象辅助工具的雷达雷达开发，雷达跟踪和成像，平流层和对流层中的雷达风谱，高功率地面穿透性雷达（用于水文研究，检测危险废物，危险废物，油/天然气储量，油/天然气储量），PAGERS，PAGERS，PAGER，PAGER，手机电话系统和军事通信。 ***
