| 摘 要： | 将小波变换应用于圆谐联合变换相关器作旋转不变的目标检测。与高通滤波的圆谐联合变换相关器相比，其输出相关峰宽度、识别力、峰噪比和旋转不变性都有较大改善，小波函数采用改进的Ｍｅｘｉｃａｎ－ｈａｔ小波，圆谐联合变换相关器采用直流偏置型，给出计算机模拟实验结果。

| Abstract: | Wavelet transform is used in the circular harmonic joint transform correlator for ratation- invariant target detection. Comparing with the high pass filtering circular harmonic joint transform correlator, its correlation peak width, discrimination ability, peak-to-noise ratio, and rotation-invariant performance are better. The modified Mexican-hat wavelet is chosen as the wavelet function and the DC bias is adopted for the circular harmonic joint transform correlator. Computer simulaton results are given. |
