摘要
针对无线电引信在海杂波背景下目标检测问题的需要,在分析入射余角、工作频率、极化方式以及海面状态对后向散射系数影响的基础上,给出了海杂波对引信信杂比的影响,并对Morchin模型和双尺度粗糙面复合模型两类海面后向散射模型进行仿真和拟合;仿真结果表明:在大入射余角条件下,较双尺度粗糙面复合模型,Morchin模型能够取得更好的拟合效果,更有效地反映无线电引信超低空工作时海面后向散射系数。
Aim at the problem of target detection in the sea clutter background of radio fuze, the influence of sea clutter on fuze SINR was proposed based on the analysis of the effects of incident angle, frequency, polarization mode and sea surface state on the backscattering coefficient. The simulation and fitting of two types sea clutter backscattering model, Morchin model and double-scale rough surface compound model, were completed. The simulation results show that the Morchin model can achieve the best fit effect under the large incident cosine condition and it can reflect the sea surface backscattering coefficient of the radio fuze at low altitude, and is more effectively than double-scale rough surface compound model.
