【摘要】 与传统模拟信号处理技术相比，数字信号处理技术因在处理性能和灵活性等方面有着巨大的优势，在现代雷达信号处理领域中得到了广泛应用。数字正交检波和数字脉冲压缩是获取目标的关键步骤之一。作为雷达信号处理的重要组成部分，对其进一步的研究和应用具有一定的实际指导意义。本文首先介绍了雷达信号处理的相关理论，并结合系统功能和技术指标要求，给出了采集处理系统的总体设计方案以及具体的硬件实现；完成了数字正交检波、数字脉冲压缩、自适应副瓣对消和副瓣匿影的工程实现。此外，本文还阐述了网络接口和链路口等通信接口的设计。最后，给出了采集处理系统的测试方案，实测结果均能满足雷达系统的技术指标要求，验证了设计的正确性。更多还原

【Abstract】 Compared with the traditional analog signal processing, digital signal processingtechniques has a huge advantage in terms of processing performance and flexibility,andit has been widely applied in the field of modern radar signal processing.Digitalorthogonal demodulation and digital pulse compression is one of the key steps to obtainthe target. As an important part of radar signal processing, it has some practicalguidance for further research and application.This paper starts with the related theory involved with radar signal processing,thencombined with the system features and technical specifications,puts forward the overalldesign of acquisition and processing system as well as specific hardware architecture.Later,the implementation of digital orthogonal demodulation,digital,adaptive sidelobecancellation,pulse compression and sidelobe blanking is illustrated in detail.The paper isalso focused on the design of network interface and linkport. Finally,the systemmeasurement is performed to prove the system’s correctness.更多还原
