摘要
雷达高分辨距离像在实现自动目标识别方面具有较大潜力,其识别性能与雷达系统参数,如雷达工作频率、信号带宽等有关。此外,用于采集识别器训练数据的雷达接收机的特性与实际工作的雷达接收机的特性会有所不同,也会影响到识别性能。文中对上述参数对识别性能的影响进行了分析和评估,所得到的结果对目标识别雷达的系统设计具有参考价值。
Radar high range resolution profile（HRRP） is a promising signature for radar automatic target recognition（ATR）, its recognition performance is a function of radar system parameters, such as transmitted signal bandwidth, carrier frequency, etc. In addition, the channel responses of different radar receivers may be different, which also will lead to a reduction of recognition performance. In this paper, the effect of radar system parameters on HRRP recognition performance is analyzed and evaluated, the results obtained are helpful for ATR radar design.
