Detection Performance Assessment of Near-space Hypersonic Target Based on Ground-based Radar

摘要

摘要: 针对不同地基雷达(GBR)部署方式对探测临近空间高超声速目标的性能影响问题，该文建立临近空间高超声速目标模型和GBR探测模型，依据目标雷达截面积(RCS)、探测距离和观测角随时间的变化情况，提出检测概率、跟踪系数和资源冗余率3种雷达探测性能评估指标，仿真分析GBR前沿部署、接力部署和要地部署方式对临近空间高超声速目标探测性能的影响。结果表明，前沿部署和接力部署相结合的探测效果好，前沿部署首次发现目标距离远，能提供的预警时间长，要地部署跟踪时间短，资源冗余率高。研究结果具有一定现实意义和工程实践性，能为临近空间预警系统中GBR部署提供理论依据和技术支撑。

Abstract: Aiming at the problem that different Ground-Based Radar (GBR) deployment way influences the detection performance to the near-space hypersonic target, the near-space hypersonic target model and GBR detection model are established. On the basis of target Radar Cross Section (RCS), detection distance and angle with the change of time, the detection probability, tracking coefficient and resource redundancy rate of 3 kinds of radar detection performance evaluation indicators are put forward, GBR forward deployment, relay deployment and reclaiming deployment way affect the detection performance to near-space hypersonic target are simulation analyzed. The results show that the detection effect of forward deployment combines relay deployment is good, forward deployed found the target distance for the first time is far that can provide the longer warning time, the tracking time of reclaiming deployment is short and has high resource redundancy rate. It has certain practical significance and engineering practical and can provide a theoretical basis and technical support to the deployment of GBR for near-space early warning system.
