论文摘要
高功率干扰器是宽带通信渠道中的主要障碍之一。为此，本文提出了一种宽带干扰物检测方法。提出的技术是通过将传入信号作为输入进行采样，并产生检测到的干扰器的频率和功率读数。检测方法依赖于驱动开路存根，在该存根中，电压与干扰物的功率成正比，而直立波模式是其频率的指示。这种方法比具有较宽动力动力范围的多功能带宽可行。该概念进行了设计和优化分析，并为概念验证而建立了原型。测得的结果表明，在1--16 GHz频率范围内检测干扰物的能力范围在-20至20 dBm之间。检测概念还配备了不同类型的可调式带挡滤波器（BSF），以自动检测和抑制干扰物，如果其功率超过了可编程阈值。在测得的响应时间为500 ns的情况下，提出的方法是宽带接收器的技术推动剂。
High-power interferers are one of the main hurdles in wideband communication channels. To that end, this paper presents a wideband interferer detection method. The presented technique operates by sampling the incoming signal as an input, and produces the frequency and the power readings of the detected interferer. The detection method relies on driving an open circuit stub, where the voltage is proportional to the power of the interferer, and the standing wave pattern is an indicator of its frequency. This approach is feasible over multi-octave bandwidth with a wide power dynamic range. The concept is analyzed for design and optimization, and a prototype is built for a proof-of-concept. The measured results demonstrate the ability to detect an interferer within the 1--16 GHz frequency range, with a power dynamic range between -20 to 20 dBm. The detection concept is also fitted with different types of tunable bandstop filters (BSFs) for automatic detection and suppression of the interferer if its power exceeds a programmable threshold. With a measured response time of 500 ns, the presented method is a technology enabler for wideband receivers.
