摘要
建立了一种螺旋桨回波散射点叠加模型(BSPS)。给出了基于逆合成孔径雷达(ISAR)成像的螺旋桨调制模型(IBJEM)。根据螺旋桨的ISAR回波特性,对三种有不同螺旋桨结构的桨叶回波进行了成像仿真,讨论了螺旋桨结构参数对桨叶回波特性的影响。研究结果表明:该模型有较大的实用价值。
The superposition model of back scattering point （BSPS） of propeller was established in this paper. The jet engine modulation based on inverse synthetic aperture radar （IBJEM） imaging was given out. The propeller echo of three propellers with different structures was simulated according to the ISAR echo characteristics of the propellers. The effects of the structure parameters of the propellers on the characteristics of the propeller echo were discussed. The results showed that this model had certain practical value.
