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

摘要

摘要: 針對不同地基雷達(dá)(GBR)部署方式對探測臨近空間高超聲速目標(biāo)的性能影響問題，該文建立臨近空間高超聲速目標(biāo)模型和GBR探測模型，依據(jù)目標(biāo)雷達(dá)截面積(RCS)、探測距離和觀測角隨時(shí)間的變化情況，提出檢測概率、跟蹤系數(shù)和資源冗余率3種雷達(dá)探測性能評估指標(biāo)，仿真分析GBR前沿部署、接力部署和要地部署方式對臨近空間高超聲速目標(biāo)探測性能的影響。結(jié)果表明，前沿部署和接力部署相結(jié)合的探測效果好，前沿部署首次發(fā)現(xiàn)目標(biāo)距離遠(yuǎn)，能提供的預(yù)警時(shí)間長，要地部署跟蹤時(shí)間短，資源冗余率高。研究結(jié)果具有一定現(xiàn)實(shí)意義和工程實(shí)踐性，能為臨近空間預(yù)警系統(tǒng)中GBR部署提供理論依據(jù)和技術(shù)支撐。

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.
