【摘要】：箔条云团雷达回波的建模与仿真一直是电子对抗领域研究的热点之一。为反映不同雷达极化、不同入射方向等条件下雷达回波的差异,在有关单根箔条运动模式、后向散射特性等已有研究成果的基础上,首先通过分析视线及其极化分量与雷达天线和箔条的角度关系完善了演绎法建模的理论研究。其次设计了基于统一计算设备架构(compute unified device architecture,CUDA)的CPU与GPU串并行计算程序,解决了演绎模型仿真时计算量大的难题。最后从雷达回波的距离-多普勒特性、幅度分布特性等多个方面对仿真结果进行了分析,并通过与外场实测和理论推导数据的对比验证了仿真结果的可信性。
[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.
