Testbed for RF signal identification and positioning based on antenna arrays and software-defined radio (SDR)

泰雷兹研究与技术公司（TRT）魁北克市研究中心的研究人员需要一个无线电信号识别和地理定位系统的功能测试平台。该系统需要多个采集站，每个采集站都配备一个自适应天线阵列和一个现场可编程门阵列（FPGA），以支持软件定义无线电（SDR）原型。本提案代表了该试验台开发的第一阶段，并基于Roy教授及其团队在自适应天线阵列、SDR和地理定位方面的专业知识。考虑到所提议的测试平台的非常雄心勃勃的范围，最初的6个月阶段将限于两个方面：1-开发，在实际SDR硬件上实现，以及验证基于智能天线阵列的无线电信号到达方向（DOA）估计的适当校准方案；开发了一种基于软件仿真的地理定位和射频信号识别算法。

Researchers at the Thales Research and Technology (TRT) Quebec City research center require a functionaltestbed for a radio signal identification and geolocation system. This system would entail multiple acquisitionstations, each equipped with an adaptive antenna array and a Field-Programmable Gate Array (FPGA) in orderto support software-defined radio (SDR) prototyping. The present proposal represents the first phase in thedevelopment of this testbed, and is based upon the expertise of Professor Roy and his team in adaptive antennaarrays, SDR, and geolocation.Given the very ambitious scope of the proposed testbed, this initial 6-month phase will be limited to twoaspects: 1- development, implementation on actual SDR hardware, and validation of an appropriate calibrationscheme for radio signal direction-of-arrival (DOA) estimation based on smart antenna arrays; 2- developmentof a geolocation and RF signal identification algorithm in context based on software simulation alone.
