Recently, the direction-of-arrival (DOA) estimation using an array antenna has been studied extensively. Accordingly, array calibration method has also become an important topic. Conventional data acquisition methods often require a positioner or an azimuth table to make sources of known DOAs for pre-measurement of array calibration in a radio anechoic chamber. However, such a measurement is both...
It is difficult to implement three-dimensional (3D) measurement in small field of view (FOV) or confined space with traditional sensors, for they cannot be put into or operated flexibly in such circumstances. To solve the problem, a sensor constructed by an electronic endoscope and a pair of mirrors is designed, combining the flexible characteristics of the endoscope transmission wire and the advantages...
