[1] A technique for the estimation of total liquid water content (LWC; the sum of cloud water and rainwater contents) using simultaneous S and Ka band scanning radar observations is proposed and tested using the National Center for Atmospheric Research simultaneous S band and Ka band dual‐polarimetric (S‐PolKa) radar system. The sources of error for this wavelength pair are evaluated, and the m...

the major problems of common classification method are their noisy outputs, computational complexity and a lack of expert knowledge in the classification process. this paper proposed an object-oriented and knowledge based method for classification of polarimetric sar data. multi resolution method was selected for image segmentation. also, the main idea to extract knowledge is to use polarimetri...

Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...

Abstract. Accurate precipitation estimation with weather radars is essential for hydrological and meteorological applications. The differential reflectivity (ZDR) a crucial radar measurement that helps to improve quantitative estimates using polarimetric radars. However, system bias between the horizontal vertical channels generated by produces an offset in ZDR. Existing methods calibrate ZDR m...

the purpose of this study is the fusion of polarimetric sar and hyperspectral images for concealed target detection in forest areas. the proposed method is using the polarimetric and the spectral signatures. a radarsat-2 image and a hyperion image of the city san francisco were chosen for evaluation of the proposed method. the four targets were selected in the forest and the outer areas. three ...

Abstract. Data from weather radars are commonly used in meteorology and hydrology, but they burdened with serious disturbances, especially due to the appearance of numerous non-meteorological echoes. For this reason, these data subject advanced quality control algorithms. The paper presents a significant improvement RADVOL-QC system made necessary by an increasing number various disturbances. N...

In this paper, the problem of target detection in phased-MIMO radars is considered and target detection performance of phased-MIMO radars is compared with MIMO and phased-array radars. Phased-MIMO radars combine advantages of the MIMO and phased-array radars. In these radars, the transmit array will be partitioned into a number of subarrays that are allowed to overlap and each subarray transmit...
