The experimental, results show that the algorithm can against arbitrary rotation with a rather high speed and a rather high matching rate, and it is robust to scale transform with low noise.
实验数据表明，该算法可抗任意角度旋转、匹配速度较快、正确率较高，而且对噪声小的尺度变化具有良好的鲁棒性。
When Doppler frequency shift is very low for the very slow speed of a ship drawing alongside, it is rather difficult to detect ship's speed with a general CW Doppler Radar.
由于船舶靠岸速度很低，多普勒频移很小，利用一般连续波多普勒雷达检测船舶靠岸速度，困难较大。
