Djuth 9304571 A high speed radar processor for improved studies of the Earth's ionosphere and upper atmosphere. Many emerging techniques for the operation of large radar facilities used for atmospheric research require high data throughput rates and computer processing speed. As a result, much of the data is averaged in a way that adversely affects the spatial and temporal resolution of the measurements. The computer system developed as part of this Phase II SBIR award will greatly increase the utility of a variety of existing radar systems through the use of a flexible, high-performance radar processor. Preliminary tests at Arecibo Observatory in Puerto Rico indicate that major improvements i the resolution and accuracy of the radar observations can be achieved through the implementation of computationally intensive radar techniques. The Massively Parallel Spectral Processor developed under this award can be directly applied to a wide range of large to mid-sized radar systems used to probe the Earth's atmosphere. It can also be adapted for imaging radar applications, incorporated into certain tactical radar systems, and converted into a processor for the nuclear sciences. ***

Djuth 9304571 用于改进地球电离层和高层大气研究的高速雷达处理机。 许多用于大气研究的大型雷达设施的操作的新兴技术要求高数据吞吐率和计算机处理速度。 因此，许多数据的平均方式对测量的空间和时间分辨率产生不利影响。 作为第二阶段SBIR合同的一部分，该计算机系统将通过使用灵活的高性能雷达处理器，大大提高各种现有雷达系统的实用性。 在波多黎各的阿雷西博天文台进行的初步试验表明，通过采用计算密集型雷达技术，可以大大提高雷达观测的分辨率和准确度。 根据该奖项开发的大规模并行光谱处理器可直接应用于用于探测地球大气层的各种大中型雷达系统。 它也可以适用于成像雷达应用，纳入某些战术雷达系统，并转换为核科学的处理器。 ***
