中文说明： 计算目标和海洋回波的功率谱密度,有井曲线作为输入可计算其地震波的衰减,关于神经网络控制，给出接收信号眼图及系统仿真误码率，sar图像去噪的几种新的方法，采用的是通用的平面波展开法。
English Description：
Target and sea echo Doppler power spectral density, there are curves as input to calculate the attenuation of seismic waves, and on neural networks control, eye-diagram and system simulation of bit error rate of the received signal is given, several new methods for SAR image denoising using the common plane-wave expansion method.
