Study of detection performance of passive bistatic radars based on FM broadcast

引用

Journal of Systems Engineering and Electronics 2007年第1期18卷 22-26页

作者： shan Tao Tao Ran Wang yue zhou Siyong Dept. of Electronic Engineering Beijing Inst. of Technology Beijing 100081 P. R. China

The passive bistatic radar based on the FM broadcast has inherent superiority with respect to its survivability. In this article, the ambiguity function （AF） and the cross ambiguity function （CAF） of the FM radio signal are analyzed and illustrated. The Kolmogorov Smirnov （K-S） test verifies that the amplitude probability density function of the CAF side lobes is exponential; the distribution of the target is also deduced. Finally, the detection performance of the passive radar is studied, and the result shows that this new type bistatic radar has favorable detection capability.

利用基于计算机视觉的接触式位移识别技术分析结构振动视频来捕捉结构层间位移响应,可以解决极端荷载作用下结构层间位移观测困难的问题。结合结构层间变形机理与多特征检测算法,提出了结构弯剪耦合变形识别方法,并在理论上验证了该方法在结构发生多种变形情况下的适用性。该方法利用倾角仪数据与视觉识别结果计算得到结构的层间位移、有害层间位移、无害层间位移及部分位移在总位移中的占比,并在缩尺模型振动台试验中验证了该方法的准确性与有效性。研究结果表明,该方法可用于建筑结构在地震过程中的关键变形监测,即通过结构不同层间变形成分的比例可以准确判断结构各层实际受力状态。该方法通过多数据计算显著提高了层间位移的识别精度,为建筑层间受力状态评估提供了重要依据。
