Abstract

In addressing the challenge of tracking moving targets at sea, our focus has been directed towards the development of a reconstruction methodology founded upon satellite orbital manoeuvres. This endeavour has led us to devise a predictive model for manoeuvres within a geographic coordinate system, alongside the creation of a three-phase orbital manoeuvre model. A Non-dominant Sorting Adaptive Memetic (NSAM) algorithm is proposed in this paper, which is a two-layer multi-objective optimization algorithm that retains the advantages of evolutionary algorithms based on the population’s evolution and has an excellent local optimization ability of local search algorithms. The proposed algorithm can be used to solve multi-objective optimization problems. By comparing the target observation results before and after the satellite reconstruction simulation, it can be concluded that the orbital manoeuvring can effectively improve the observation probability and observation duration of the target at a certain speed. The orbital manoeuvre model created in this paper provides a certain methodical support for the tracking problem of moving targets at sea.

用于海上运动目标跟踪的天基探测卫星星座重构方法研究

在应对跟踪海上移动目标的挑战时，我们的重点是开发一种基于卫星轨道机动的重建方法。这一努力使我们设计了一个地理坐标系内机动的预测模型，同时创建了一个三阶段轨道机动模型。本文提出了一种非显性排序自适应记忆（NSAM）算法，它是一种两层多目标优化算法，保留了基于种群进化的进化算法的优点，并具有优异的局部搜索算法的局部优化能力。该算法可用于求解多目标优化问题。通过比较卫星重建模拟前后的目标观测结果，可以得出结论，轨道机动可以在一定速度下有效提高目标的观测概率和观测持续时间。本文建立的轨道机动模型为海上运动目标的跟踪问题提供了一定的系统支持。

期刊介绍： Applied Sciences (ISSN 2076-3417) provides an advanced forum on all aspects of applied natural sciences. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
