对图像的去噪处理，包括了加权梯度领域去噪、高斯模板去噪和两种方法的结合(Denoising of images, including the weighted gradient field denoising, Gaussian model for denoising and the combination of two methods)

有关“高光谱遥感图像的小波去噪方法”的文章！写的不错(Hyperspectral Imagery Denoising Method Based on Wavelets)

说明：  逆合成孔径雷达仿真舰船图像，包括舰船的俯仰、滚动、偏航运动。(Inverse synthetic aperture radar image simulation of ship, including the ship' s pitch, roll, yaw movement.)

趋势面分析是拟合数学曲面的一种统计方法。通常要找到一个合适的曲面精确表达实际问题往往比较困难，但却可以利用多项式函数来近似逼近它。(trend surface analysis is fitting surfaces of a mathematical statistical methods. Usually to find a suitable surface accurately reflect the actual problems are often more difficult, but polynomial function can be used to approximating it.)

说明：  本例用matlab解决了数学建模中飞机精确定位问题。使用了优化函数‘constr’解决。（请在matlab 6.5以下运行）(Using matlab to solve this case, the mathematical modeling of precise positioning of the aircraft. The use of optimized function ' constr' solution. (Please run the following in matlab 6.5))

This paper deals with the modeling of the statistical distribution of the effective gain of terminals. This incorporates both the characteristics of the antenna’s radiation pattern in the situation of use, and the characteristics of the local propagation environment. A frequency-wise and frequency-correlated log-normally-distributed effective-gain model is proposed as a standard model of wide – although not universal – validity. This is done mainly for the sake of simplicity and ease of use. This model is tested in a few exemplary cases of measured and simulated terminals, using a subset of the WINNER channel model for the local propagation.

这是一个综合性的仿真程序。包括：用matlab生成一个FIR滤波器，得到滤波器系数及阶数；再用C语言产生一个混合频率的数字信号，之后将生成的数据样点送入到DSP主程序进行数字滤波，DSP主程序算法用的是循环缓冲区算法，这一部分在CCS上实现。(This is a comprehensive simulation program. Comprising: generating a matlab FIR filter, to obtain the filter coefficients and order then mixed to produce a C-frequency digital signal, and then the resulting data samples into the main program to the DSP for digital filtering, DSP main algorithm using a circular buffer algorithm, this part of the CCS to achieve.)
