摘要
针对SAR对抗效能评估中的欺骗干扰效果推算难题,提出了一种基于点扩展函数PSF的SAR有源欺骗干扰效果的评估与推算模型。首先,推导了SAR系统响应的能量解析式及其误差容限;其次,给出了基于PSF的SAR有源假目标干扰效果的推算模型与步骤;最后,分析了复高斯杂波背景下模型的推算性能。仿真实例表明了模型的准确性和有效性。
Aiming at calculation problem of deception jamming against SAR, the evaluation and calculation model of SAR active deception jamming based on Point Spread Function are proposed. Firstly, the energy analytical formula for impulse re- sponse of the system and its error model are derived. Secondly, the equivalent calculation model is given. At last, the performance is analyzed. Simulation shows that the model has validity and accuracy.
