SBIR Phase I: Modular Approach to Scientific Radar Design

* 96-61180朱特 这个小型企业创新研究（SBIR）第一阶段项目将开发固态发射/接收模块，这些模块针对地球大气层、电离层和磁层的遥感进行了优化。 这些单元将为新一代UHF相控阵雷达铺平道路，大大提高系统性能和灵活性。 预计系统成本明显低于传统雷达。 第一阶段将开发一种新的固态功率放大器、互补天线设计和改进的低温发射/接收开关。 从高功率管放大器转移到分布式固态单元将被检查。 新的雷达可以配置为从天顶到低仰角快速跟踪动态地球物理事件。 由于系统结构是模块化的，它非常适合于雷达干涉测量，并可以逐步扩展到一个强大的非相干散射雷达的尺寸特性。 一个非常高灵敏度的雷达将需要4000-5000个模块。 潜在的商业应用包括非相干散射雷达的开发、机载“硬目标”的雷达跟踪和成像、气象辅助设备、平流层和对流层的雷达风廓线、高功率地面穿透雷达（用于水文研究、危险废物探测、石油/天然气储备）、寻呼机、蜂窝电话系统和军事通信。 ***

*** 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. ***
