摘要
针对雷达高分辨距离像(HRRP)的幅度敏感性,现有HRRP雷达自动目标识别(RATR)方法一般简单地能量归一化.本文借鉴切空间距离的思想,提出一种利用HRRP回波强度信息提高识别精度的方法,实测数据仿真试验证明与传统方法相比,该方法可提高识别率约5个百分点.
Radar high-resolution range profile (HRRP) is sensitive to amplitude-scale, which is overcame through simply normalizing the amplitude-scale to unit energy by most available HRRP radar automatic target recognition (RATR) approaches. In light of the tangent distance, we propose two algorithms to improve HRRP recognition performance using amplitude information. Experiments based on measured data shows our algorithms have a larger average recognition rate than that of the regular method by about 5 percentage points.
