【摘要】：海洋生態(tài)已經(jīng)成為人類不可或缺的一部分,海洋經(jīng)濟也越來越受到各國的重視。與此同時,海洋安全成為了國防建設(shè)的重要環(huán)節(jié)。本文就海上監(jiān)測設(shè)備高頻地波雷達(High Frequency Surface Wave Radar, HFSWR)與船舶白識別系統(tǒng)(Automatic Identification System, AIS)的信息融合關(guān)聯(lián)工作展開研究。首先,將HFSWR與AIS系統(tǒng)的探測數(shù)據(jù)作為研究對象；然后,對兩種數(shù)據(jù)信息進行特征提取、數(shù)據(jù)預(yù)處理、濾波更新、點跡關(guān)聯(lián)等處理；最后,通過處理結(jié)果得出目標的合作與非合作狀態(tài)和其他相關(guān)信息。本文的研究目的是分析AIS與HFSWR所測數(shù)據(jù),結(jié)合二者的優(yōu)點得到信息互補,通過合適的點跡關(guān)聯(lián)算法,實現(xiàn)對海上目標的實時跟蹤和探測。通過信息融合減少重復(fù)跟蹤,提高探測效率,重點關(guān)注非合作目標,保障海上安全�；谘芯磕康�,本文研究的工作包括針對HFSWR與AIS兩種數(shù)據(jù)信息的特點,提取兩種數(shù)據(jù)的特征參數(shù)。由于兩種信號源信號采集頻率不同,在時間維度用線性插值法與外推預(yù)測法來實現(xiàn)時間校準。由于所處的坐標系不同,采用球面坐標系去實現(xiàn)空間統(tǒng)一。在數(shù)據(jù)預(yù)處理之后,利用相關(guān)分析統(tǒng)計法與粒子濾波概率數(shù)據(jù)濾波(PF-PDA)點跡關(guān)聯(lián)融合,對海上目標進行狀態(tài)評估。利用仿真環(huán)境與實時數(shù)據(jù),驗證兩種算法的可行性與有效性。數(shù)據(jù)結(jié)果表明,算法具有一定的工程應(yīng)用價值和可行性。
[Abstract]:Marine ecology has become an indispensable part of human beings, and marine economy has been paid more and more attention by various countries. At the same time, maritime security has become an important link in national defense construction. In this paper, the information fusion association between high frequency surface wave radar (HFSWR) and Automatic Identification system (AIS) is studied. First, the detection data of HFSWR and AIS system are taken as the research objects; then, the feature extraction, data preprocessing, filtering and updating, point trace correlation and other processing of the two kinds of data information are carried out. By processing the results, the goal of the state of cooperation and non-cooperation and other relevant information. The purpose of this paper is to analyze the data measured by AIS and HFSWR, and to obtain complementary information by combining the advantages of the two, and to realize the real-time tracking and detection of marine targets by appropriate point trace association algorithm. Through information fusion to reduce repeat tracking, improve detection efficiency, focus on non-cooperative targets, to ensure maritime security. For the purpose of research, the work of this paper includes extracting the characteristic parameters of HFSWR and AIS according to the characteristics of HFSWR and AIS. Due to the difference of signal acquisition frequency between the two sources, linear interpolation and extrapolation prediction are used to calibrate the time in time dimension. Because the coordinate system is different, the spherical coordinate system is used to realize the spatial unification. After data preprocessing, correlation analysis statistics and particle filter probabilistic data filtering (PF-PDA) correlation fusion are used to evaluate the state of marine targets. Simulation environment and real-time data are used to verify the feasibility and effectiveness of the two algorithms. The results show that the algorithm has certain engineering application value and feasibility.
