Radar Data Transmission System Based On The Ethernet Physical Layer Chip Design

Ground radars, set in specified or rough remote areas where there are less or no human supervisions, need to communicate with the control/display center through an efficient data transmission system. Typically, such a data transmission system can be of either digital microwave or digital fiber optic or cable communication. Compared with cable or microwave, fiber optic communication has a much brighter prospect in ground radar data transmission applications by characterizing large capacity, long distance transmission, less disturbing signals, high data transmission quality, anti-electromagnetic interference, good confidentiality, small size and light weight for convenient construction. Among the networking technologies, Ethernet is pretty mature with transmission speed up to 1000Mb/s in fiber optic communication and therefore is an ideal solution for radar data transmission applications. However, Ethernet is designed and developed based on computer communication and its protocols are relatively complicated and hard to realized from hardware side. This thesis represents an innovative and reliable remote radar data transmission solution by overcoming this problem with a well-developed Ethernet physic layer chip, purpose oriented home made protocols and single film fiber. A sample system has already been made and tested. The result shows that this innovative solution is reliable and applicable. Chapter 1 gives a preface to this thesis and main works performed to realize this solution is presented subsequently in chapter 2, 3, 4 and 5 as below.
