摘要
针对逆合成孔径雷达(ISAR)成像对抗中的基于数字图像合成(DIS)技术欺骗干扰方法,在分析现有基于频率调制率微调的抗DIS欺骗干扰方法工程实现方面缺陷的基础上,通过将基于压缩感知理论的随机抽取采样和稀疏重构方法融入到信号接收和处理部分中,提出了基于压缩感知理论的改进抗DIS欺骗干扰方法,进一步提高基于频率调制率微调抗DIS欺骗干扰方法的工程实用性。仿真实验结果显示了基于压缩感知理论的改进抗DIS欺骗干扰方法的有效性。
Aiming at deceptive jamming method based on digital image synthetic(DIS)for inverse synthetic aperture radar imaging,the lack in engineering realization of anti-DIS deceptive jamming method based on variation of frequency modulation rate was analyzed and improved method for anti-DIS deceptive jamming based on compressed sensing theory was put forward.The improved method adopted compressed sampling based on random selecting and sparsity reconstruction method in compressed sensing into signal receiving and processing department in the foregoing method,and engineering practicability for anti-DIS deceptive jamming method based on variation of frequency modulation rate was improved.Simulation revealed validity of the improved method.
