In this paperwepresent a local interpolation-based variant of the well-known polar format algorithm used for synthetic aperture radar (SAR) image formation.We develop the algorithm to match the capabilities of the applicationspecific logic-in-memory processing paradigm, which offloads lightweight computation directly into the SRAM and DRAM. Our proposed algorithm performs filtering, an image pe...

This paper presents an effective Polar Format Algorithm (PFA) for spotlight bistatic synthetic aperture radar (SAR) with arbitrary geometry configuration. Nonuniform interpolation and resampling are adopted when converting raw data from polar coordinates to Cartesian coordinates according to the characteristics of raw data samples in spatial frequency space. Thus, the proposed algorithm avoids ...

SAR phase history data represents a polar array in the Fourier space of a scene being imaged. Polar Format processing is about reformatting the collected SAR data to a Cartesian data location array for efficient processing and image formation. In a real-time system, this reformatting or “re-gridding” operation is the most processing intensive, consuming the majority of the processing time; it a...

Using hydrothermal synthesis process a series of Mobil Five (MFI) zeolites were synthesized with silica to alumina ratio (SAR) of 50, 100 and 200. The synthesized MFI zeolites were used to exchange with 0.5%, 1.0% and 2.0% Ca(NO3)2 solutions for modification of MFI zeolites to Ca-MFI zeolite. The formation of MFI zeolite phases was identified by XRD and FT-IR analysis. TGA...

Water scarcity in the hill tract districts of Bangladesh becomes acute dry season as most streams, primary source water, up. However, groundwater, where available, can supply water throughout year. In this study, a total 37 samples were collected and analyzed from shallow (34) deep (3) wells Khagrachhari Sadar to assess their geochemical type suitability for drinking using multiparameter ground...

Incubation of the four purified HMG-CoA reductase phosphatases with the sodium salts of eleven polycarboxylic acids at concentrations of 40 mM, inactivated the enzymes to different degrees depending on the structure of the carboxylic acids. Maleate, malonate, oxalate, citrate, and hydroxymethylglutarate produced full inactivation at the concentration tested. When the four phosphatases were incu...

biodiversity plays a crucial role in stability and productivity of natural ecosystem. the main goal of this research was to classify ecological groups in steppe rangeland and investigate their relationships with plant diversity indices. therefore, fifty different land unit tracts (lut) were identified in khod-neuk basin, yazd province, iran, in 2010. vegetation and soil samples were taken in th...
