SAR欺骗干扰工程化设计研究

Research on SAR deception jamming on engineering design

对SAR雷达的欺骗干扰研究在理论模型方面已经有了大量深入的研究,但对该领域在工程化设计方面的研究报道很少。首先给出了SAR欺骗干扰机的系统组成,然后分析了大数据量卷积模块的分段分相流水处理方法。在此基础上,给出了DRFM模块的硬件实现方案。结合硬件,提出了一种简单有效的闭环等效验证方法,并采集实际数据做了验证试验。试验效果证明了该硬件方案的有效性。最后,分析了SAR欺骗干扰机走向实用化所需的进一步研究的内容和方向。

SAR deception jamming has been researched largely and deeply but mainly on theorily modeling. Reports on engineering design is very few in this field. Firstly, compositive modules of SAR deception jamming system are proposed, and then mass data convolution using subsection multiphase pipeline method is analyzed. Hardware implemented project of DRFM is provided on this basis. Secondly, orte of closed loop validated method which is simple and effective is proposed and validated experiment has been done by using practical data. The result shows that the method is validated. Lastly, research content and direction are analyzed for further engineering design.
