Abstract: Nowadays, as the emerging of new targets and pattern of operations, along with the operational environment becoming more complex, relying only on the capability of single radar is much more difficult to meet the increasing operational requirements. Therefore, this paper carries on the research of the networked radar which is kind of new system radar. By analyzing the developing status, trend and key technologies of foreign networked radar, we summarize the experience and enlightenment which can provide developing references to the networked radar system of our country.
