图像传感器，体积小，工作电压低，提供单片VGA摄像头和影像处理器的所有功能。通过SCCB总线控制，可以输入整帧、子采样、取窗口等方式的各种分辨率8位影像数据。-The image sensor, small size, low operating voltage, with all the functionality of monolithic VGA camera and image processor. Controlled by SCCB bus, can enter various re

In this paper, we firstly construct a wide-band undersampling array, then present a novel frequency and direction of arrival (DOA) estimation method for a very wide frequency band (2-18GHz). Choosing a set of appropriate sampling frequencies and
