Abstract
A system comprising a radar subsystem including a radar transmitter and a radar receiver, and an encoder subsystem including a computer connected to a transmitter and two antennas. The computer is configured to encode and transmit a custom payload AIS Type 8 message. A second computer connected to a receiver and antenna receives the message. The custom payload AIS Type 8 message contains target longitude, latitude fields, range, and bearing fields.A method for transmitting and receiving the radar track of a target ship including: receiving the radar signal at the own ship; encoding the target ship longitude, latitude, speed, and course into a custom payload AIS Type 8 message; transmitting the custom message to a receiver ship; decoding and displaying the target ship longitude, latitude, course, and speed at the receiver ship.
