英文摘要： Direction finding technology, which plays an important role in the application of radar, electronic warfare, communication, is rapidly developing in recent years. This project on the optically controlled phased array direction finding based on the optically controlled phased array and modeling, through the mechanism of direction finding algorithm based on spatial spectral estimation as the main line, with optically controlled phased array and mutual influence of direction finding algorithm as the core, carry out the broadband phased array spatial spectrum estimation research on direction finding problems. This research aims to put forward a new set of suitable for broadband optical phased array direction finding method, in order to know how to choose reasonable parameters to achieve optimal resolution direction finding and direction finding precision and solve the problem of broadband optical phased array direction finding on a specific optical phased array beam forming conditions, and promote further development of the research of optical phased array in turn.
