针对传统性能评估指标难以有效评估检测前跟踪(TBD)算法性能的问题，构建了TBD算法性能评估通用流程，并从单帧检测和虚警、航迹检测和虚警及计算资源3个方面，建立了一套基于单目标模型的性能评估指标体系。在此基础上，比较了 Hough 变换和递推贝叶斯滤波2种典型 TBD算法的性能，仿真结果验证了该指标体系的有效性。
針對傳統性能評估指標難以有效評估檢測前跟蹤(TBD)算法性能的問題，構建瞭TBD算法性能評估通用流程，併從單幀檢測和虛警、航跡檢測和虛警及計算資源3箇方麵，建立瞭一套基于單目標模型的性能評估指標體繫。在此基礎上，比較瞭 Hough 變換和遞推貝葉斯濾波2種典型 TBD算法的性能，倣真結果驗證瞭該指標體繫的有效性。

A performance evaluation process is proposed to deal with the problem that the traditional performance metrics being hard to evaluate the Track-Before-Detect(TBD) algorithms effectively. Some performance evaluation metrics based on single target are proposed, from three aspects including single frame detection and false alarm, track detection and false alarm, and computing resources. On that basis, the performances of Hough transform and recursive Bayesian filtering are compared in simulation, which verifies the validity of the performance evaluation metrics.
