目的 研究合成孔径雷达 (SAR)对海面波成像的机理和海面波对雷达截面的调制机理 .方法 选用速度聚束模型 ,采用不同参数仿真 SAR对海面波成像的情况 .结果 由于海面波的运动 ,使得 SAR对海面波成像过程成为非线性 ,使 SAR图像在方位向发生移位和模糊 .结论 用这种仿真方法研究 SAR对海面波成像是一种有效途径
Aim To study the mechanism of synthetic aperture radar (SAR) imaging of sea surface wave and the modulation mechanism of sea surface wave on radar cross section.Methods The velocity bunching model was used to simulate sea surface wave with different parameters.Results Due to the movement of sea surface wave, Making the SAR non-linear to the sea surface wave imaging process, shifting and blurring the SAR image in the azimuth direction.Conclusion It is an effective way to study the SAR imaging of the sea surface using this simulation method
