In this article, we present the development and integration of an existing cost-effective, open-source software-defined radio (SDR) receiver into a complete, pulsed-radar system used to study meteor reflections that ablate in the Earth's atmosphere. The use of SDR technology in radar applications is not, in itself, a new concept, but details regarding construction of back-end processing, formatting, and storage have not been widely discussed. More specifically, SDR systems, in general, are used to provide a communication link, meaning that precise time of arrival and signal levels are not of primary importance, but these parameters are critical in a radar system. This article addresses in detail methods used to redesign an existing, open-source receiver into a pulse-synchronized radar system for use by anyone interested in cost-effective radar data acquisition solutions. Additionally, we provide test data from an experimental observation to validate operation and performance of the resulting system.

GnuRadar：用于雷达应用的开源软件定义无线电接收器平台

在本文中，我们介绍了现有经济高效的开源软件定义无线电 (SDR) 接收器的开发和集成，用于研究地球大气中消融的流星反射的完整脉冲雷达系统。在雷达应用中使用 SDR 技术本身并不是一个新概念，但有关后端处理、格式化和存储的构建的细节尚未得到广泛讨论。更具体地说，SDR 系统通常用于提供通信链路，这意味着精确的到达时间和信号电平不是最重要的，但这些参数在雷达系统中至关重要。本文详细介绍了用于重新设计现有、将开源接收器集成到脉冲同步雷达系统中，供任何对具有成本效益的雷达数据采集解决方案感兴趣的人使用。此外，我们提供来自实验观察的测试数据，以验证最终系统的操作和性能。
