Differential phase shift φDP is the phase shift between the horizontally polarized wave and the vertically polarized wave.
Notes
• Since φDP is not affected by attenuation, it can be used to develop and check attenuation correction schemes. • Attenuation correction based on using the total Differential Phase Shift as a constraint is selectable for reflectivity products. Reflectivity products can be viewed with or without attenuation correction. Correction of Differential Reflectivity due to differential attenuation is also available.
