The invention discloses a target tracking algorithm for marine navigation radar ARPA (Auto Radar Plotting Aids), which comprises the steps of acquiring an identified ARPA target data table, setting the size of a window, carrying out target matching, realizing data interconnection, and then setting smooth values alpha and beta; calculating the dynamic information of a shipping track; carrying out smoothing filtering, and finally updating the ARPA target data table. The target tracking method provided by the invention has strong practicality and overcomes the defects that the existing ARPR products are easy to loss targets and the target parameters are unstable; and the method can track the target well in a ship-dense environment that the ships go in or out of a navigation channel, etc.
Description
[0001] technical field [0002] The present invention relates to the technical field of marine navigation radar, especially used in the field of marine navigation radar ARPA (Auto Radar Plotting Aids, automatic radar plotting instrument), specifically a marine navigation radar ARPA target tracking algorithm. [0003] Background technique [0002] Marine navigation radar, also known as marine radar, is mounted on a ship and is an indispensable system for determining the position of the ship and preventing collision accidents. Marine navigation radar realizes the functions of navigation avoidance, ship positioning and piloting by accurately capturing the position information of other ships, land, route marks and other objects, and displaying them on the display screen. Traditional ARPA is realized by special hardware circuit, which limits the complexity of ARPA algorithm in realization. With the innovation of radar structure, the current ARPA function has become a function...
