摘要
雷达系统是舰船的信号采集与通信单元,具有非常重要的作用。通常,在军事舰船上配置相控阵雷达进行敌方船只侦察等任务,但是相控雷达存在功率大、耗电量高、电子元件容易老化的缺点,而三坐标雷达具有更精确的信号探测能力和更高的覆盖率,且功耗较小,因此成为业内的研究重点。本文研究的主要内容是船载三坐标雷达的信号处理问题,由于三坐标雷达的工况存在大量的噪声等干扰信号,必须对雷达信号进行降噪、过滤等处理。本文开发了一种基于FPGA的雷达信号处理系统,显著提高了雷达系统的信号处理效率。
Radar system is a signal acquisition and communication unit of ship, and plays a very important role. The phased array radar is usually equipped with phased array radar for reconnaissance of enemy ships, but the phased radar has the disadvantages of high power, high power consumption and easy aging of electronic components. The coordinate radar has more accurate signal detection ability and higher coverage rate, and has a smaller power consumption. Therefore, it has become the research focus of the industry. The main content of this paper is the problem of signal processing ship three coordinate radar, three coordinate radar working conditions due to the existence of a large number of noise signal, we must deal with the noise and filtering of radar signal. In this paper, a radar signal processing system based on FPGA is developed,which significantly improves the signal processing efficiency of radar system.
