ATR系统性能与目标类型数的分析与建模

自动目标识别(ATR)系统性能评估需要综合考虑工作环境变化和系统代价约束。针对地面目标识别的应用背景,结合宽带雷达平台分析了待识别目标类型的数目对ATR系统性能的影响,并考虑了系统存储代价的作用。分别得到了两个适合空地背景的ATR系统扩展性的经验模型。所得模型和相关结论为空地背景下ATR系统的性能预测和评价提供了借鉴和参考,具有一定现实意义。

Analysis and modeling for ATR system performance and target type numbers

The extended operation condition(EOC) and system cost are two key factors in automatic target recognition(ATR) system performance evaluation.For the problem of air-to-ground(A-G) targets recognition with wide-band radar,this paper analyzes the influence of target type number on ATR performance and also the effect of system storage cost.An experiential extensibility model of two suitable ATR systems is built in the paper.The experiential model and the corresponding conclusions have useful reference to ATR system performance prediction and assessment in many practical A-G applications.
