| Abstract | 瞬态信号对射电天文观测的影响越来越大，开发射频信号检测系统，可提升瞬态干扰检测能力，为进一步的瞬态信号特征分析提供重要技术支撑。本文基于USRP X310和GNU Radio平台，采用多相滤波、快速傅里叶变换、积分处理等，开发了微秒量级射频信号检测系统，实现了140 MHz实时带宽、30 MHz～6 GHz工作带宽、0.5μs时间分辨率的信号检测，并通过实测给出了检测系统的幅度测量精度、动态范围。实例应用表明，本文系统可应用于电子设备的辐射发射测量和电磁环境瞬态信号测量，为射电望远镜电磁兼容设计和干扰缓减提供技术支持。 |
| Other Abstract | Transient signals are having an increasingly significant impact on radio astronomy observations. Developing radio frequency signal detection systems to enhance transient interference detection capabilities provides vital technical support for further transient signal characteristic analysis. Based on the USRP X310 and GNU Radio platform, we utilize techniques such as polyphase filtering, FFT transformation, and integral processing. We have developed a microsecond-level radio frequency signal detection system, achieving a real-time bandwidth of 140 MHz, operating bandwidth from 30 MHz to 6 GHz, and a time resolution of 0.5 μs. Through practical measurements, we provide the amplitude measurement accuracy and dynamic range of the detection system. Based on this foundation, through practical applications, we demonstrate that this system can be applied to radiation emission measurements of electronic devices and transient signal measurements of electromagnetic environments, providing technical support for electromagnetic compatibility design and interference mitigation in radio telescopes. |
