| 摘要: |
| 为有效评估地面目标的伪装性能，提出了一种采用地基合成孔径雷达(Ground Based-Synthetic Aperture Radar，GB-SAR)模拟观测获取目标SAR信息的试验和伪装性能评估方法。该方法在分析伪装目标的SAR成像特性的基础上，采用地基机动平台上的SAR系统对地面伪装目标进行模拟卫星SAR观测几何的数据获取，在此基础上通过目标散射特性分析等实现伪装性能评估。首先分析了地基SAR系统模拟星载SAR侦察的必要性；其次，介绍了适用于模拟星载SAR观测的典型地基SAR系统组成。针对伪装性能评估，介绍了如何从目标特性的角度分析伪装效果的方法；并指出了该方法适用于多种雷达伪装设备的评估。 |

| Abstract: |
| A method of acquiring targets signatures and camouflage performance assessment using ground based synthetic aperture radar(GB-SAR) simulation observation was put forward for effective evaluation of the land military targets camouflage performance. The method was on the basis of targets SAR imaging characteristics analysis, according to simulating data acquisition of spaceborne SAR observation geometry, based on which camouflage performance assessment was realized through scattering characteristics analysis. The necessity of spaceborne SAR reconnaissance simulation utilizing GB-SAR system was analyzed. A typical GB-SAR system suitable for the simulation was introduced. The way to assess camouflage effect from the view of target characteristics was introduced. It was put forward that the method is appropriate for radar camouflage equipment evaluation. |
