Improved Estimation of the Specific Attenuation and Backscatter Differential Phase over Short Rain Paths

In radar polarimetry, the differential phase CDP consists of the propagation differential phase FDP and the backscatter differential phase dhv. While FDP is commonly used for attenuation correction (i.e., estimation of the specific attenuation A and specific differential phase KDP), recent studies have demonstrated that dhv can provide...

Adaptive and high-resolution estimation of specific differential phase for polarimetric X-band weather radars

One of the most beneficial polarimetric variables may be the specific differential phase K_DP because of its independence from power attenuation and radar miscalibration. However, conventional K_DP estimation requires a substantial amount of range smoothing as a result of the noisy characteristic of the measured...
