摘要
该文提出一种基于目标电磁散射模型的逆合成孔径雷达(ISAR)空中目标欺骗干扰算法,利用目标电磁散射模型对雷达回波进行调制,能够模拟遮挡、多次散射等目标散射特征,并包含目标的平动、姿态等运动特性,保证了虚假目标的逼真性。该算法计算量小,具有较强的实时性。通过仿真试验验证了欺骗干扰算法的有效性,并对算法的计算复杂性进行了分析。
Based on the electromagnetic scattering model, an algorithm of deception jamming for Inverse Synthetic Aperture Radar （ISAR） aerial target is proposed. The simulated data of electromagnetic model is utilized to modulate the ISAR echoes, and thus the scattering characteristics of the target, such as shading and multiple scattering, can be simulated. Besides, the motion characteristics, such as translation and attitude, are also included These ensure the fidelity of the false target. The proposed method requires less computation amount and is capable of real-time realization. Simulation results verify the effectiveness of the algorithm, and the computation complexity of the algorithm is also analyzed.
