COLLABORATIVE RESEARCH: Application of the Coded-Long-PulseRadar Technique to Studies of Thermal Balance in the Ionosphere

编码单脉冲技术在电离层热平衡研究中的应用本项目由地球空间研究公司和犹他州立大学合作完成。这项研究计划有两个组成部分，包括电离层的雷达观测和相关的建模工作。雷达波的非相干散射产生两种不同的信号：离子线和等离子线。通常，雷达实验要么使用其中一种，要么使用另一种，但地球空间研究公司部分开发的一种新技术可以同时测量离子线和等离子线。雷达实验将在波多黎各的阿雷西博和欧洲的EISCAT设施进行。所得数据提供了电离层等离子体密度和热特性的一套全面的测量。当与建模相结合时，测量结果将用于研究影响电离层观测行为的许多不同过程。

Application of the coded lone-pulse technique to studies of thermal balance in the ionosphere This project is a collaborative effort involving Geospace Research Inc. and Utah State University. The research plan has two components including radar observations of the ionosphere and an associated modeling effort. Incoherent scatter of radar waves produces two distinct signals: an ion line and a plasma line. Usually, radar experiments are performed using either one or the other, but a new technique partly developed by Geospace Research Inc. allows both ion line and plasma line to be measured simultaneously. The radar experiments are to be performed at Arecibo in Puerto Rico and with the EISCAT facility in Europe. The resulting data provides a comprehensive set of measurements of the density and thermal properties of the ionospheric plasma. When combined with modeling, the measurements will be used to study a number of difference processes that affect the observed behavior of the ionosphere.
