Shipboard aircraft landing auxiliary decision-making method and device based on wave measurement

Abstract

The invention discloses a shipboard aircraft landing auxiliary decision-making method and device based on wave measurement, and belongs to the field of overall design of ships. The method comprises the steps that wave height distribution in the ship advancing direction is determined based on a radar signal, in the ship advancing direction, measured by wave measuring radar; the wave height is measured through a target wave measurement buoy; the wave height measured by the target wave measurement buoy is adopted as the standard, the wave height distribution measured by the wave measuring radar is corrected, and the wave height distribution about to be encountered by the ships in next m minutes is obtained; and according to the wave height distribution about to be encountered by the ship in the next m minutes, a seakeeping quick forecasting technique is adopted for forecasting the motion of the ships in the next m minutes, a self-adaptation correction technique based on very short-range forecasting is adopted for carrying out self-adaption correction on the measured actual motion of the ships and the motion forecast theoretically, the corrected motion result of the ships in the next mminutes is obtained and compared with a shipboard aircraft landing criterion to complete auxiliary decision making. According to the shipboard aircraft landing auxiliary decision-making method and device based on wave measurement, a more precise forecasting result can be obtained.

Description

technical field [0001] The invention belongs to the field of overall ship design, and more specifically relates to a wave measurement-based auxiliary decision-making method and device for carrier aircraft landing. Background technique [0002] In order to improve the safety of ship landing operations and reduce the probability of accidents, many countries are vigorously developing carrier-based aircraft landing assistance guidance systems. One of the key technologies is the short-term prediction technology of ship motion. The short-term prediction technology of ship movement can predict the future movement attitude of the ship in advance, allowing real-time correction of the landing guidance parameters of the carrier-based aircraft, ensuring that the carrier-based aircraft lands within the predetermined landing range and improving the safety of operations . [0003] The key factor affecting the safe landing of carrier-based aircraft is the interference effect of the large s...
