Analysis of ALTAIR 1998 meteor radar data
[1] We describe a new analysis of a set of 32 UHF meteor radar traces recorded with the 422 MHz Advanced Research Project Agency Long‐Range Tracking and Identification Radar facility in November 1998. Emphasis is on the absolute velocity measurements and inferences that can be drawn from them regarding the meteoroid masses and mass densities. We find that the 3‐D velocity versus altitude data c...
متن کاملComputer Analysis of X-Band Radar Data
Dual polarized X-Band Synthetic Aperture Radar (SAR) data were obtained for a test site in South Carolina containing a variety of forest and agricultural cover types, as well as water and urban areas. The optically correlated images were digitized with a scanning microdensitometer using a 40 ~m aperture. Digi tal registration of the two polarizations was more difficult than anticipated due to g...
متن کاملfuzzy dynamic multi-objective data envelopment analysis model (fdm-dea)
data envelopment analysis (dea) is a managerial powerful tool for assess the performance of decision making units (dmus). nowadays, multi-objective dea models are an attractive technique for evaluation quantity and quality aspects of performance analysis. but these models are in static. in this paper, we want to present a proposed fuzzy dynamic multi-objective dea model in which data are changi...
متن کاملAdaptive Fusion of Inertial Navigation System and Tracking Radar Data
Against the range-dependent accuracy of the tracking radar measurements including range, elevation and bearing angles, a new hybrid adaptive Kalman filter is proposed to enhance the performance of the radar aided strapdown inertial navigation system (INS/Radar). This filter involves the concept of residual-based adaptive estimation and adaptive fading Kalman filter and tunes dynamically the fil...
متن کاملShapley value-based multi-objective data envelopment analysis application for assessing academic efficiency of university departments
This paper adopts a modified approach of data envelopment analysis (DEA) to measure the academic efficiency of university departments. In real-world case studies, conventional DEA models often identify too many decision-making units (DMUs) as efficient. This occurs when the number of DMUs under evaluation is not large enough compared to the total number of decision variables. To overcome this l...
