摘要
随着雷达、计算机、软件等技术的迅猛发展,软件化雷达技术成为未来发展的必然趋势和选择。为此,研究基于CPU平台的数字波束形成(DBF)技术实现。根据DBF技术原理和雷达回波数据块的特点,把DBF计算过程拆分成可以独立并行执行的过程,并在基于CPU的平台上实时实现。测试结果表明,基于CPU的DBF技术处理方案能够满足软件化雷达对DBF技术的功能性和实时性的要求。
With the rapid development of radar,computer,software and other technologies,software based radar technology has become an inevitable trend and choice of future development.Therefore,this paper studies the implementation of digital beam forming(DBF)technology based on CPU platform.Based on the principles of DBF technology and the characteristics of radar echo data blocks,the DBF calculation process is divided into independent and parallel execution processes,and implemented on a CPU platform in real-time.The test results indicate that the CPU-based DBF technology processing scheme can meet the functional and the real-time requirements of software based radar for DBF technology.
