Abstract: 雷達追蹤系統中,多目標追蹤(Multiple-Target Tracking, MTT)是不可缺少的重要技術。追蹤系統是否能夠正確的預估目標物的真實軌跡其中牽涉兩個問題:資料結合(Data Association technique)與變速度(Maneuvering)檢測。本研究提出運用競爭式類神經網路(Competitive Hopfield Neural Network, CHNN)特殊的運算架構,發展一資料相關結合運算的程序,以輔助雷達追蹤系統。本研究同時運用影像處理技術,考慮目標物的形態與外觀等,提高目標物被辨認的機率,降低預估的誤差。影像經前處理後,接著擷取目標物的特徵,並運用相似度函數進行影像特徵辨識,最後,以結構相似度(Structural Similarity, SSIM),求得目標物的影像數值資訊,同時配合CHNN 資料結合技術與適應性程序追蹤輔助架構,能更準確追蹤目標。經模擬結果顯示,本研究提出的演算法能在複雜的追蹤環境中,有效降低追蹤多個變速度目標時的追蹤誤差。
Multiple-target tracking (MTT) is a prerequisite step for radar surveillance systems. Data association is the key technique in a radar multiple -target tracking system. A new approach to data association using both quantity data and image information is investigated in this project. In order to combine two different attributes, a fusion algorithm based on the Competitive Hopfield Neural Network (CHNN) is developed to match between sensor measurements and existing target tracks. When target maneuvering problems are occurred, an adaptive multiple-model maneuvering estimator is applied. Based on the computation algorithm, we convince that this approach can successfully solve the multiple -target tracking problems and have better performance.
