Problems solved by technology

[0003] Since there is no specific reference object at sea, it is difficult to determine the position and speed change of a ship on a ship formation, so the determination of the position and speed of a ship in a ship formation is usually done by means of radar, but a ship in a formation The number is large, and it is blocked by ships to detect in a large range, and as the detection range increases, the accuracy will decrease. In view of this, the present invention proposes a dynamic supervision and control algorithm for ships based on radar surround

Abstract

The invention relates to the technical field of ship supervision, in particular to a ship dynamic supervision control algorithm based on radar surrounding. The method comprises the steps of setting a supervision control center; detecting nearby ships and boats; the data information is transmitted back to the supervision control center; the returned data information is checked; and sending the control instruction to a controlled point in the range of the main detection radar. According to the invention, the surrounding environment is detected through the auxiliary detection radar carried on the controlled point, and the detected data information is transmitted back to the supervision control center, so that the detected data information on the controlled point is stored on the basis of the main detection radar, and the supervision range of the supervision control center is expanded. Moreover, the adjacent auxiliary detection radars form verification data in the returning process, and the verification data are matched to check the data information, thereby greatly improving the accuracy of returning the data information.

Description

technical field [0001] The invention relates to the technical field of ship supervision, in particular to a dynamic supervision and control algorithm for ships based on radar surround. Background technique [0002] Radar finds targets and determines their spatial position by using radio methods. Therefore, radar is also called "radiolocation"; radar is an electronic device that uses electromagnetic waves to detect targets. Radar emits electromagnetic waves to irradiate targets and receive their echoes , thereby obtaining information such as the distance from the target to the electromagnetic wave emission point, the distance change rate (radial velocity), the azimuth, and the altitude. [0003] Since there is no specific reference object at sea, it is difficult to determine the position and speed of the boat in a boat formation. Therefore, the determination of the position and speed of the boats in the boat formation is usually done with the help of radar. The detection is ...
