海杂波后向散射频谱的研究

为研究导弹跟踪海面目标时的海杂波多径干扰,建立了用于数值仿真和半实物仿真的目标回波与海面杂波的多普勒频率及功率模型。理论仿真计算值与飞行试验数据的比较表明,所建的海面后向散射海杂波模型正确,可用于背景模型仿真。最后给出了一低空远界理论弹道主瓣杂波功率的仿真样例。

Backscatter Spectrum Research of Sea Clutter

To study the multipath interference of sea clutter in missile tracking sea surface target,the Doppler frequency and power models of target echo and sea clutter using in numerical simulation and hardware-in-the loop simulation were founded in this paper.The comparison of the calculation results and flight test data showed that the sea backscattering model of sea clutter was proper,which could be used for background model simulation.At last,a simulation example of main lobe clutter power for low altitude and far field theory trajectory was presented.
