Wide-band digital signal processing with application in electronic warfare

摘要:

宽带数字信号处理是电子战研究的主题之一。相对于窄带而言，宽带会导致数字动态、灵敏度、多信号处理等变差。针对这些问题，结合现代先进的电子技术，介绍了宽带数字信号处理中的宽带采集、阵列处理、数字信道化以及数字储频干扰等技术，分析了宽带对这些技术的影响，探讨了宽带数字信号处理技术在电子战中的应用及发展方向，为研究数字信号处理技术的工程师提供有益的参考。

Abstract:

Wide-band signal processing is one of the topics in electronic warfare. In contrast to narrowband signal processing, wideband signal processing can result in the worsening of digital range，sensitivity and multiple signals processing，etc. To tackle these problems，this paper introduces some modern advanced electron technologies，including wideband sampling，array processing，digital channelizing，and jamming based on the digital radio frequency memory etc. in wideband digital signal processing，and analyses the effects of bandwidth on these technologies. It discusses the applications and the development trends of the technologies in electronic warfare. It is expected that the topic could provide useful reference for engineers engaging in the digital signal processing.
