54467 战斗机飞行员海上遇险搜救的核心是获取遇险定位信息， When the pilot is in maritime distress, the most important thing about rescue is to obtain distress location information.
54468 由于受海上气象、浪涌等多种因素影响，手持和穿戴式救生终端选择恰当的时机快速发起遇险位置报告的相关能力较弱。 However, due to the complexity of the weather and conditions, The pilot's hand-held life-saving communications equipment has become less effective, and power consumption has also increased significantly.
54469 以飞行员某装备北斗RDSS短报文有效发射为研究对象， This paper studies the application of short message communication in Beidou satellite navigation system at sea.
54470 利用深度神经网络，提出一种海上环境下发射时机学习预测模型，将高度、经纬度、方向、俯仰角、电量、速度、加速度等参数转换为单精度浮点数输入深度神经网络， Based on the deep neural network, this paper proposes a prediction model which converts the parameters of height, latitude and longitude, direction, pitch angle, electric quantity, velocity and acceleration into single precision floating-point input depth neural network.

54472 海上目标监视系统实时获取并长期积累了大量轨迹数据，深入挖掘分析其中蕴含的目标行为特征，是提升传统的基于声光电磁特性的海上目标探测技术性能的重要途径。 The maritime target monitoring system acquires a large number of trajectory data, deep mining and analysis of the target behavior characteristics is an important way to improve the performance of the traditional maritime target detection technology based on acoustic, optical and electromagnetic characteristics.
54473 在轨迹聚类、轨迹预测和行为分析等数据挖掘的预处理环节中，主流的轨迹分段算法以最小化损失为分段依据，没有给分段轨迹赋予行为模式等语义内涵，限制了分段轨迹的应用范围。 In the pre-processing of data mining, such as trajectory clustering, trajectory prediction and behavior analysis, the mainstream trajectory segmentation algorithm aims to get the minimum loss and does not give the semantic meaning to the segmented trajectory, which limits the application of segmented trajectory.
54474 对此，本文提出一种基于行为模式的海上目标轨迹分段算法， This paper proposed a segmentation algorithm of maritime target trajectory based behavior pattern.
54475 通过定义七种目标行为模式，制定行为模式优先级，达到轨迹分段的目的。 Seven target behavior patterns were defined to achieve the goal of trajectory segmentation.
54476 实验分析表明，本文的算法能准确合理的进行轨迹分段并真实的还原轨迹，不同的算法参数对应不同的应用场景。 Experiment shows that the algorithm in this paper can segment the trajectory accurately and restore the trajectory accurate, different algorithm parameters correspond to different application scene.
