音频信号降采样程序 支持48k->8k 24k->8k 8k->1k 的降采样.实现方法,先做低通滤波,再做采样点抽取.低通滤波起使用67点FIR,系数由matlab使用窗函数法生成 (Audio signal down-sampling procedures to support the 48k-)

一般模式的机载双基地合成孔径雷达回波数据产生，收发平台具有不同的速度与方向，均工作在斜视模式(General pattern of airborne bistatic synthetic aperture radar echo data generated transceiver platform has a different speed and direction, are working in the squint mode)

MATLAB例子，执行与Integra系列热电偶扫描( Matlab Example to Perform a Thermocouple Scan with Integra Series )

This is to experiment with feature detection and tracking algorithms. In particular, the reader should gain intuition on the role of various design parameters such as the size of the windows for selection and tracking, the SSD criterion and thresholds.
