“…Which is accepted functional relations for the attenuation of frequency vs rain and wind emissivity. [3] There are measurements available at specific times in the Atlantic basin from sensors attached on research aircraft, but not in other hurricane basins have ability of aircraft exploration. Even the hurricanes in the Atlantic are out of range of the aircraft for most of their lifetimes.…”

There is a huge consideration in the use of microwave airborne radiometry for remote sensing instead of satellite, the important role of airborne way is how to provide high accuracy real time data. The airborne hurricane tracking is an important method compared with the space borne method, which is developed by NASA Marshall Space Flight center to provide high resolution measurements. By flying special aircraft equipment using synthetic thinned array radiometry technology and included all critical measurements such as hurricane eye location, speed of wind and the pressure. This paper describes the data analysis of best track positions for Hurricane Gonzalo based on the date collected by airborne microwave radiometry. Significant analysis comes from comparing the airborne data with the surface observations from ship reports. The vast majority is to estimate peak intensity and minimum central pressure of Gonzalo from 12 to 19 October 2014, based on blend of SFMR flight-level winds and pressure retrievals from observing brightness temperatures. SFMR: Stepped-Frequency Microwave Radiometer is a highly developed tool developed by the Langley Research Center that is designed to measure the wind speed at the ocean's surface, and the rain fall rates within the storm accurately and continuously. The work also addresses the realistic details of the locations and the valuable information about the pressure and wind speed, which is very critical to predict the growth and movement to get the idea for future monitoring of the hurricane disasters. Also presents a conceptual of step frequency microwave radiometer in airborne side. The objective of this research is tracking analysis techniques based on comparing the satellite, ship and airborne reports to get higher accuracy. The system operates at four spaced frequencies in the range between 4 GHz and 7 GHz provides wide measurements between ± 45 incidence angle. Gonzalo 2014 is an example; the best results of retrieved wind speed, locations and pressure are presented. There are several national projects have been developed for earth observation, such as fire, hurricane and border surveillance. In this work, the efficient high resolution techniques of C-band, four-frequency, the work also addresses a valuable information comes from the airborne system and the prediction way of the growth and movement of hurricanes. In passive microwave remote sensing from space at C band has the penetrating advantages of atmosphere. Airborne system is able to work in full Polari-metric in four bands, C, X, S, L and P-band, which cover the wavelengths from 3 to 85 cm. The modes of measurement contain single channel operation wavelength and polarization.
