| 摘 要： | 双基地角在杂波单元内的连续变化导致宽波束双基地高频雷达的海杂波谱不同于窄波束.为了揭示这种差异,在G ill和W alsh窄波束双基地海面雷达散射截面积(RCS)基础上,提出了宽波束双基地海面RCS模型;结合高频地波雷达方程,得到宽波束双基地海杂波功率谱密度模型,通过仿真计算得到海杂波谱的具体形态.理论分析和仿真结果表明,在发射机附近以及基线附近的雷达探测区域,宽波束海杂波谱具有明显的展宽效应.

| Abstract: | For bistatic high-frequency(HF) radar,the receiver beam width is usually broad,so the bistatic angle over a clutter cell is a variable.This will cause the spread of Bragg lines in contrast to the narrow beam case.Based on Eric Gill's narrow beam HF cross sections of the ocean surface,broad beam HF bistatic cross sections of the ocean surface were presented and the results were obtained by numerical simulation.Then these results were used to obtain the power spectral density(PSD) of the broad beam bistatic o... |
