本论文探讨使用软件定义无线电（SDR）创建一个基于SDR的辐射计，能够执行相同的操作作为一个传统的辐射计，并提供额外的功能，没有发现在传统的辐射计。传统的辐射计需要精心设计以确保正确的操作，通过尽快将RF信号数字化并在软件中处理该信号，可以简化辐射计的硬件设计。数字辐射计以前已经探索过，但通常使用定制的组件。软件定义无线电技术已经变得越来越普遍，并且现在可以获得具有高性能的经济实惠的商用现成（COTS）SDR。本文利用COTS软件无线电技术实现并评估了一个基于软件无线电的辐射计。这将降低辐射计的成本，并有助于使辐射计更容易为更广泛的受众所使用。传统的辐射计的功能映射到我们提出的基于SDR的辐射计检查。然后，传统的和基于SDR的辐射计之间的性能进行了实验评估。此外，本论文探讨如何实现SDR辐射计可以帮助减轻射频干扰。
This thesis explores using a software defined radio (SDR) to create a SDR-based radiometer that is capable of performing the same operation as a traditional radiometer and offers additional capabilities not found in traditional radiometers. Traditional radiometer requires careful design to ensure correct operation, by digitizing the RF signal as soon as possible and processing this signal in software, the hardware design of the radiometer can be simplified. Digital radiometers have been explored before, but often use customized components. Software defined radio technology has become more widespread, and affordable Commercial Off The Shelf (COTS) SDRs are now available with high performance. This thesis leverages a COTS SDR technology to implement and evaluate a SDR-based radiometer. This will lower the cost of the radiometer and help make radiometers more accessible to a wider audience. The mapping of the functionality of a traditional radiometer to our proposed SDR-based radiometer is examined. Then an experimental evaluation of the performance between a traditional and SDR-based radiometer is conducted. Additionally this thesis explores how the implemented SDR-based radiometer can help mitigate radio frequency interference.
