| Abstract | ALOS-2, which was launched on the 24th of May 2014, is equipped with a fully polarimeric L-band SAR (PALSAR-2) [1, 2]. Unlike ALOS-PALSAR, which used to collect polarimetric (PLR) data at one incidence
angle (about 22°) [3], PALSAR-2 offers the possibility of providing PLR measurements at various beams (FP6-3 to FP6-6), with incidence angle varying from 25° to 35° [4]. Recently, several investigations [5, 6, 8, 9] have been conducted on the
assessment and calibration of polarimetric ALOS2, in the context of the ALOS2 calibration-validation (Cal-Val) working group. PALSAR-2 distortion matrix is measured using CRs deployed in the Amazonian forest [5]. The extended Freeman-Van Zyl
calibration method introduced in [7] is used for accurate assessment of PALSAR-2 calibration parameters [6]. Six data sets collected over the Amazonian forest (with CRs) are used to assess PALSAR-2 distortion matrix for five beams (FP3 to FP7) with
incidence angle varying from 25° to 40°. It is shown that PALSAR2 antenna is highly isolated with low cross-talk (lower than -40 dB) [6]. These results are in agreements with the ones obtained in [8, 9] with different calibration methods. |
