【摘要】:箔條云團雷達回波的建模與仿真一直是電子對抗領(lǐng)域研究的熱點之一。為反映不同雷達極化、不同入射方向等條件下雷達回波的差異,在有關(guān)單根箔條運動模式、后向散射特性等已有研究成果的基礎(chǔ)上,首先通過分析視線及其極化分量與雷達天線和箔條的角度關(guān)系完善了演繹法建模的理論研究。其次設(shè)計了基于統(tǒng)一計算設(shè)備架構(gòu)(compute unified device architecture,CUDA)的CPU與GPU串并行計算程序,解決了演繹模型仿真時計算量大的難題。最后從雷達回波的距離-多普勒特性、幅度分布特性等多個方面對仿真結(jié)果進行了分析,并通過與外場實測和理論推導(dǎo)數(shù)據(jù)的對比驗證了仿真結(jié)果的可信性。
[Abstract]:The modeling and simulation of chaff cloud radar echo has been one of the hotspots in the field of electronic countermeasures. In order to reflect the difference of radar echo under different radar polarization and incident direction, based on the research results of single chaff motion mode and backscattering characteristics, Firstly, the theoretical research of deductive modeling is improved by analyzing the angle relationship between the line of sight and its polarization component, radar antenna and chaff. Secondly, a parallel computing program between CPU and GPU is designed based on the unified computing equipment architecture compute unified device architecture data, which solves the problem of large computational complexity in the simulation of deductive model. Finally, the simulation results are analyzed from the range-Doppler characteristics and amplitude distribution characteristics of radar echo, and the credibility of the simulation results is verified by comparison with the field measurements and theoretical deduced data.
