摘要

目前，空间碎片探测方面的研究越来越受重视，曲靖非相干散射雷达的建成进一步加快了我国空间碎片探测的步伐.本文基于曲靖非相干散射雷达基本特性，首先利用Mie理论研究了498MHz、500MHz和502MHz三个频率理想球形目标的散射特性并进行了分析，结果表明目标大部分散射能量分布在前向及其附近方向；然后以编目为14209的空间碎片为例，通过该雷达的探测得到其后向雷达散射截面（RCS）为0.0043m

，并给出了该雷达的最小可探测目标，这说明了曲靖非相干散射雷达在空间碎片探测方面具有优良的性能，目标电磁散射截面按500MHz计算正确有效，并能够满足工程需要.最后，以西安7.3m和1m天线为例分析了该结论对非相干散射雷达优化布站以及组网探测空间碎片具有参考价值.

Abstract

At present

more and more people pay attention to space debris detection

and the completion of the Qujing incoherent scattering radar has further accelerated the pace of China's space debris detection. Based on basic characteristics of this radar

firstly Mie theory is used to study the scattering characteristics of an ideal spherical target at 498MHz

500MHz and 502MHz

respectively

the results show that most scattering energy distribute in and near the forward direction;For space debris cataloged by 14209

we obtained its radar cross section (RCS) 0.0043m

and gave the minimum detectable object for this radar

which indicated that the radar had excelle

nt performance in space debris detection

and the calculation was precise and could meet the needs of the project. Finally

through the example of 7.3m and 1m antenna in Xi'an

we analyse the conclusion

which is valuable for optimize embattle and network detection of space debris.
