residual wavefront phase error 波面补偿剩余误差
In synthetic aperture sonar imaging, the residual phase error is mainly corrected via autofocus.
合成孔径声呐成像中，主要通过自聚焦校正剩余相位误差。
The phase balance of the central frequency can ensure the accuracy of the correlation phase, and the residual phase error will only reduce the coherency.
实现信道中心频率的相位精度就可以保证干涉相位的精度，而通道内的残余相位差只会引起干涉相关度的降低。
With this method, the time delay is estimated firstly, then the residual phase error. Through this way the movement error range that can be compensated by this algorithm is extended.
该方法首先估计时延，然后再对剩余误差进行相位估计，从而扩大了算法适用的运动误差范围。
