雷达中频目标回波，线性调频脉冲多普勒起伏模型！希望对亲有帮助！！(IF radar target echo Doppler downs chirp model! I hope to help the pro! !)

利用卡尔曼滤波器进行信道估计 提示：信道估计的状态方程和测量方程可分别表示为 要求：给出信道均方误差随样本数增加的曲线，给出matlab程序及具体的估计过程。 (Use of Kalman filter channel estimation Tip: the state of the channel estimation and measurement equations could be specified as required: given the channel mean square error increases with the number of samples to increase the curve, given the estimated matlab program and the specific process.)

matlab平台上实现函数y=sinx的逼近程序，构造bp算法实现（输出层采用y=x线性函数，隐含层采用非对称Sigmoid函数）(matlab platform function y = sinx approximation procedures, construction bp algorithm (output layer using linear function y = x, hidden layer use of non-symmetrical Sigmoid function))

该程序是music谐波恢复算法仿真，由仿真结果证明music算法可以准确进行谐波估计。(The program is music harmonic retrieval algorithm simulation, the simulation results show that the harmonic music algorithm can accurately estimate.)

这是一个很好的课件，关于系统动力学的跟轨迹的一些问题，希望对广大朋友有所帮助。(control system notes)

计算机控制理想最小拍控制器的设计实例，带有零阶保持器的对象。(Ideal for computer control of minimum film controller design example, with zero-order to maintain the target device.)

该程序可以实现图片的拖拽，放大和缩小等简单的处理。(The program can drag images, zoom in and out such simple treatment.)

this is for non linear sliding mode

(1) 读取n副连续有重叠部分的图像，在n副图像中检测SIFT特征，并用SIFT 特征描述子对其进行描述。 (2) 匹配相邻图像的特征点，并根据特征点向量消除误匹配。 (3) 使用RANSAC方法，确定变换参数。 (4) 图像融合 ((1) Read n successive overlapping sub-part of the image, the image of the n sub-SIFT features detected and characterized using SIFT descriptors be described. (2) adjacent to the image feature point matching, and according to the feature vector to eliminate false matching points. (3) using RANSAC approach to determine the transformation parameters. (4) image fusion)
