天籁射电阵的空间碎片探测性能分析
|
摘要
提出以曲靖非相干散射雷达作为一种可能的发射源与天籁射电阵组成一套双基地雷达空间碎片探测系统,对该系统的空间碎片探测性能进行计算与仿真分析,包括可探测目标雷达散射截面积(RCS)、天籁射电阵对空间目标与碎片探测时间、探测效率等。分析表明,该系统具有探测直径10 cm以下级空间小碎片的潜力,并在最后提出了一种基于该系统的交叉波束的确定方法及对空间碎片定位的方法。
A bistatic radar system combined with the Tianlai radio telescope array and an incoherent scattering radar,which is assumed as a source of transmission in Qujing,Yunnan Province,is proposed to detect the space debris. The detection performance of the system,including the radar cross section( RCS),the detection time and the detection efficiency of the Tianlai radio telescope array is calculated and analyzed in the paper. The analysis shows that the system has the potential ability to detect small space debris whose diameter is less than 10 cm,and then provides the methods of determining the cross beams and positioning space debris based on this system.
