range_sensor_layer
The range_sensor_layer is a plugin for the LayeredCostmap in costmap_2d, that uses the sensor_msgs/Range message. It is intended for use with sonar and infrared data.
The Range messages are integrated into the costmap by using a probabilistic model.
Cells with a probability higher than the mark_threshold are marked as lethal obstacles in the master costmap. Cells with a probability lo

C#七巧板-C#创建菱形图案，其间使用了进程，示例适用于 Windows 窗体，它需要 PaintEventArgse，一个 OnPaint 事件对象。代码执行下列操作：
创建两个路径：一个为头朝上的三角形，另一个为头朝下的三角形。将第二个路径添加到第一个路径上。将最终的路径绘制到屏幕。
设置控件样式为双缓冲，可以有效减少图片闪烁的问题(Create a diamond pattern C# tangram-C#, during which use of the process, the example applies to Windows Forms, and it requires PaintEventArgs e, an OnPaint event object. The code performs the following actions: create two paths: a head-on the triangle, another triangle upside down. Add a second path to the first path. Draw the final path to the screen. Set the control style for double buffering, the picture flashes can be effective in reducing the problem)

针对信号自适应chirplet分解未知参数多、实现起来比较困难的特点，文献[1]提出了一种新的chirplet分解快速算法。该算法利用计算信号的二次相位函数，得到其能量分布集中于于信号的调频率曲线上的结论，此时通过谱峰检测可同时获得chirplet调频率、时间中心和幅度的估计；然后通过解线性调频技术获得其初始频率和宽度的估计，仿真结果验证了本文算法的有效性。
(For the signal adaptive the chirplet decomposition of unknown parameters to achieve difficult to literature [1] proposed a new fast algorithm for chirplet decomposition. The algorithm makes use of the secondary phase of the calculated signal function, the conclusion focused on energy distribution curve to tune the frequency of the signal by the peak detection chirplet tune frequency, time center and amplitude estimates then by solving chirp technology to obtain the initial frequency and width is estimated that the simulation results demonstrate the effectiveness of the proposed algorithm.)
