摘要
根据脉冲多普勒雷达信号处理的相参性要求,提出以相位控制为基础的多普勒干扰信号产生方法。针对单通道采样结构的数字射频存储器,给出利用希尔伯特变换产生多普勒信号的数字算法。在Matlab中对多普勒干扰效果进行了仿真,对其FPGA实现方式进行了优化设计,结果表明了该算法的有效性和可实现性,最后对利用数字射频存储器实施多种多普勒干扰进行了研究。
The Doppler jamming generation approach based on phase controlling is proposed to meet the coherency requirement of signal processing of PD radars. Digital arithmetic of Hilbert transform is given in allusion to DRFM adopting single channel sampling. Doppler jamming effects are simulated by Matlab and its implement in FPGA is optimized. The results illustrate the effectiveness and feasibility of the method. Several methods of Doppler jamming against PD radars using DRFM are also studied.
