MIMO-OFDM雷达波束形成及优化。首先，MIMO-OFDM雷达和OFDM-MIMO雷达的定义在不同的期刊是不同的。这里MIMO-OFDM雷达的定义同IET期刊，即发射阵列应用频率分集。MIMO-OFDM雷达同时使用了频率分集和波形分集，当发射阵列阵元间距是接收阵列阵元间距的N倍时，虚拟孔径最大，这时波束最窄，空域分辨力最高。(Beamforming and its optimization of MIMO-OFDM radar, the definition of MIMO-OFDM radar and OFDM-MIMO radar in different journal are fifferent. the MIMO-OFDM radar is equal to IET journal, that is transmitting end is frequency diverse array. Both frequency diversity and waveforms diversity are used in MIMO-OFDM radar, while interelement range in transmitting end is N times of receiving end, the virtual aperture is maximum, and spatial resolution is maximum.)

图像的锐化和均衡，图像处理中最基本的两个处理方法，用matlab实现，算法简单，易懂(Image sharpening and balanced, the two approaches are the most basic image processing using matlab algorithm is simple and easy to understand)

we present an improved fuzzy C-means (FCM) algorithm for image segmentation by introducing a tradeoff weighted fuzzy factor and a kernel metric. The tradeoff weighted fuzzy factor depends on the space distance of all neighboring pixels and their gray-level difference simultaneously. By using this factor, the new algorithm can accurately estimate the damping extent of neighboring pixels. In order to further enhance its robustness to noise and outliers, we introduce a kernel distance measure to its objective function. The new algorithm adaptively determines the kernel parameter by using a fast bandwidth selection rule based on the distance variance of all data points in the collection. Furthermore, the tradeoff weighted fuzzy factor and the kernel distance measure are both parameter free. Experimental results on synthetic and real images show that the new algorithm is effective and efficient, and is relatively independent of this type of noise.
