本文研究了振幅补偿匹配滤波的旋转效应和尺度变化效应.计算机模拟的结果表明,这种滤波法对输入信号的旋转变化和尺度缩放变化,相对于传统的匹配滤波法及仅相位滤波法要敏感得多.文中还给出了这三和滤波下的相关峰值与旋转角度及尺度因子的关系曲线. In this paper, we study the rotation effect and scale variation effect of the amplitude-compensated matched filter.The results of computer simulation show that the proposed filtering method is sensitive to the change of rotation and scaling of the input signal compared with the traditional matched filter and the phase-only filter The paper also gives the relationship curve between the correlation peak and the rotation angle and the scale factor under the three and filter.
