雷达目标一维高分辨距离像的特性分析及预处理方法研究

摘要

目标高分辨距离像已经广泛应用于雷达目标识别中.但高分辨距离像对目标的运动很敏感,而且易受到杂波的干扰.针对这一问题,为了克服目标高分辨距离像的姿态敏感性和平移敏感性,利用小波去噪、平均距离像等方法得到关于目标更为稳定的高分辨距离像.对高分辨距离像的仿真实验表明,该方法获得的结果比直接结果具有更高的精度和可靠性.%High-resolution range profile is widely used in the radar target recognition.However, high- resolution range profile is sensitive to the movement of targets, and is effected by clutter noise.The wavelet denoising, mean range profile and other methods are adopted to overcome the attitude sensitivity and translating sensitivity of high resolution target range profile.The steady HRRPs were obtained with the methods.The simulation results of HRRP show that the results obtained with the methods mentioned above have higher accuracy and reliability than those acquired directly.
