matlab船舶导航雷达运动目标跟踪技术研究

摘要现今，目标跟踪技术作为雷达技术的基础，直接影响到产品质量和效率，因此无论是军方还是民用企业均对目标跟踪技术进行了深入的研究。而目标跟踪算法又是目标跟踪技术的核心内容。具体到船舶雷达的应用中，由于航道的环境相较于其他环境更复杂，雷达系统需要面对更多干扰。为了保证雷达的工作精度，我们必须更新相关技术手段。滤波算法是目标跟踪算法至关重要的组成部分，本文介绍和研究了几种滤波算法，采用了几种不同的运动模型，用matlab 进行了仿真。本文首先介绍了目标跟踪的基本原理，接着介绍了机动目标跟踪理论中的关键问题坐标系选择和目标运动方程的建立。接着具体研究了- 滤波和--   滤波，对目标进行一文运动和二文运动等不同的运动模型进行matlab 仿真，比较了滤波结果的差异，对滤波参数选取对滤波结果的影响进行了分析，最后研究了卡尔曼滤波，对于CV 模型用卡尔曼滤波器进行了matlab 仿真。   30482

Title      A study on motion target tracking technology of marine radar
Abstract Nowadays, target tracking technology has become fundamental of radar technology. It has a direct impact on the quality and efficiency of radar products. Therefore, whether military or civilian enterprises are researching tracking technology. The target tracking algorithm is the core content of the target tracking technology. When it comes to the application of marine radar, radar systems need to face more jam due to the more complex traffic compared to other environment In order to ensure the accuracy of radars’ output, we must update the related technical methods. Filtering algorithm is a very important part of target tracking algorithm. In this paper, we study several filtering algorithm, using several different motion model simulating by MATLAB. In this paper, we first introduce the basic principle of target tracking, and then introduce the selection of coordinate system and establishment of target motion equation, which are the key problem of target tracking theory. Then making a concrete research on -  filters and --    filters. Then I simulate the target of one-dimensional and two-dimensional motion different motion model by MATLAB, compare the differences in the filtering results between different models and analyze the effect of selection of parameters,. Finally, I simulate the Kalman filter with CV model by MATLAB.
Keywords: target tracking, motion model, -  filter, --    filter, Kalman filter
