SISAR側(cè)影像的校正及特征提取

Calibration and extraction of features for SISAR shadow image

  • 摘要: 在分析SISAR側(cè)影像成像機(jī)理的基礎(chǔ)上,首先分析了目標(biāo)相對(duì)于雷達(dá)的非勻速轉(zhuǎn)動(dòng)對(duì)目標(biāo)側(cè)影像的影響,同時(shí)提出了補(bǔ)償?shù)姆椒?然后分析了目標(biāo)運(yùn)動(dòng)參數(shù)對(duì)側(cè)影像的影響,在此基礎(chǔ)上提取了用于目標(biāo)識(shí)別的不變性特征,同時(shí)提出了目標(biāo)識(shí)別的方法。最后通過仿真驗(yàn)證了所提方法的正確性。
    Abstract: Based on an analysis of the principle SISAR shadow imaging, the effect on target shadow image due to nonconstant velocity rotation relative to the target is first examined, and a compensation method is also presented. In addition, the effect on target shadow image due to target motion parameters is described. Eventually, a target recognition approach on the basis of the invariable parameters obtained is proposed. The computer simulations show the efficiency of the method.
