residual phase error

基本解釋

The bifrequency correlation function of the expansion coefficients is presented and used to derive the residual phase error due to dispersion.
根據(jù)位相展開系數(shù)的雙頻相關求得了大氣色散産生的賸餘位相誤差。
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.
該方法首先估計時延，然後再對賸餘誤差進行相位估計，從而擴大了算法適用的運動誤差範圍。
As a result, the residual phase error caused by the SRC factor without range updating is reduced, so the focusing performance is dramatically improved and the effective swath width is enlarged.
第二步，該算法減小了SRC因式?jīng)]有隨距離更新所造成的賸餘相位誤差，改善了測繪帶邊緣目標的聚焦性能，極大的提高了有傚測繪帶寬；
