基于布里渊散射探测空间目标的计算分析

提出用布里渊散射原理探测空间目标的方法。分别对大气、空间目标材料金属涂层及隐身材料的布里渊散射特性进行了计算和对比分析。结果表明,大气布里渊散射频移与目标涂层及隐身材料布里渊散射频移之间相差至少大于一个数量级,由此得出利用分析布里渊散射光谱来探测空间目标的可行性。计算了散射频移的大小,并对探测技术作了分析,采用一种窄带量子滤光系统探测装置,对散射光谱进行了精确的探测和分辨。

Calculation of detecting spatial object based on Brillouin scattering

The paper gives a theoretical method of applying Brillouin scattering principle to detect spatial object.The properties of Brillouin scattering of atmosphere,metal coat of spatial object and concealed material are calculated,analyzed and compared.The result shows that the discrepancy of the frequency shifting of atmosphere,metal coat of spatial object and concealed material is at least more than 10 times,thus it is applicable to use Brillouin scattering to detect spatial objects.The article not only calculates the frequency shifting,but also studies the technique for detection,and adopts a technique of using narrow-band quantum optical filter system to distinguish the scattered light accurately.
