阵列信号处理实验研究

Some experimental results of DOA estimation

介绍了一个实际的超声阵列信号处理实验系统的实现技术及误差校正技术,包括总体结构、有源滤波接收通道、A/D 变换、中频正交采样,以及误差校正技术,该系统具有较高的稳定性.

Some techniques of system implementation and error calibration are introduced,which include system structure,active receiving channels,A/D converting,quadrature sampling and the compensation of sensor gain/phase errors and sensor locative errors.The implemented system works with high stability.
