Abstract: Emerging as a product in remote sensing systems with multiple polarizations, the specific differential phase difference provides an important input to target classification algorithms. The specific differential phase difference derived from the differential phase difference is the expression of the phase difference between two polarizations in a radar cell. The specific word refers to its formation on a cell basis. The differential phase difference is obtained accumulatively along a radar beam. Basically the specific differential phase difference is the derivative of the differential phase difference. Due to the nature of its electromagnetic propagation, the beam sent is noisily seen in the receivers. Due to this noise added to the electromagnetic wave in both polarizations and the cumulative acquisition of the differential phase difference, it becomes difficult to calculate the differential phase difference specifically on a cell basis. In this context, the propesed method reduces the noise seen in the receiver in the first stage. In the second stage, an algorithm was used to unfold the phase folds that can occur in the differential phase shift which is cumulative along the beam. Finally, linear regression with moving windows was applied on signals which noise reduced and phase folds opened, and the specific differential phase was calculated from here. © 2021 IEEE.
