摘要
论文提出了一种基于相位校正的高重频脉冲多普勒雷达自卫干扰技术,在循环复制干扰基础上增加了相位校正功能来消除相位突变,得到高质量相参的干扰信号。阐述了基于相位校正的循环复制干扰原理和设计,并对其进行了硬件实现和性能测试,对无相位校正和有相位校正两种情况下产生的干扰信号进行了比对和分析。
This research suggests a jamming technology to high-PRF pulse doppler radar based on phase calibration,which adds phase calibration to circular-replication in order to clear up phase sudden change and get high-quality coherentjamming signal. The paper elaborates the principle and design of circular-replication base on phase calibration, and implementsthe hardware , tests its performance. Besides, it also compares the jamming signal generated by with phase calibrationand without phase calibration.
