Automatic plotting system for navigation radar

Abstract

The invention provides an automatic plotting system for navigation radar. The system comprises a log, a compass, a GPS, an AIS, a radar data acquisition processing card, a transceiver unit, an industrial computer, and a control unit, wherein the log, the compass, the radar antenna transceiving unit, the AIS and the GPS are connected with the radar data acquisition processing card; the radar data acquisition processing card is inserted in a PCI slot of the industrial computer, and is in charge of receiving information transmitted by the log, the transceiver unit, the compass and the GPS, converts the information into digital information, and transmits the information to the industrial computer; the industrial computer marks a target for a radar digital signal which is transmitted by the radar according to the data acquisition processing card to acquire an accurate position of the target, and transmits the result to a display; and the control unit is connected with the industrial computer. The automatic plotting system has low cost, stable and reliable system performance and convenient maintenance.

Description

technical field [0001] The invention relates to a radar, in particular to an automatic plotting system for a navigation radar. Background technique [0002] The main function of traditional nautical radar is to observe the surrounding situation in real time with the help of radar images, without any ability to judge the target track; later, nautical radar used to manually connect targets at different times on paper charts to provide navigators with The manual plotting method of the track, but the manual plotting method has a large workload and low plotting accuracy. It is difficult to complete the plotting task in the case of multiple targets, especially it does not have the function of predicting the movement of the target. In recent years, supported by the rapid development of electronic technology, marine radar has the functions of automatic plotting and automatic tracking of targets, but because it is mainly realized by electronic circuits, it has high cost, difficult ma...

Problems solved by technology

Prior to this, foreign radar manufacturers were all based on military products. After the implementation of simplified functions, they were put into the civilian market in small batches, which did not form a market scale at all. Moreover, these radar manufacturers mainly produced military radars, supplied them to the military, and used them for civilian use. The product market capacity is small and the profit is low, so few companies specialize in the development of civilian radar (radar manufacturers in the United States and Germany have rarely been involved in the civilian radar field so far)
