Clutter suppression in an forward-looking airborne radar is different from that of an side-looking airborne radar. The clutter model of forward-looking airbore radar with amplitude and phase errors is proposed. Investigations show that the rank and spectrum of the clutter covariance matrix depends on the amplitude and phase error which decreases the performance of reduced-dimension space-time adaptive...
The cell transmission model for air traffic flow was built by Sun and Bayen. The problem of managing the flow under sector capacity constraints was formulated as an integer programming problem. However, the corresponding relaxed linear programming in their work failed to give the integer solution for the aircraft count, which is not applicable in practice. In this paper we propose the Optimal Sequential...
This paper introduces the concepts of metroplex and flexible flight. We focus on the routing part of a complete flexible flight operation. The authors establish a network data structure based on which the optimal routing algorithm is developed for the flexible flights which fly from their original airports to destination metroplexes. Moreover, the metroplex routing algorithm is performed under the...
In an earlier work, Sun and Bayen built a Large-Capacity Cell Transmission Model for air traffic flow management. They formulated an integer programming problem of minimizing the total travel time of flights in the National Airspace System of the United States subject to sector capacity constraints. The integer programming was relaxed to a linear programming for computational efficiency. In this paper...
The density of absorbable particulate matter less than 10um termed as PM10 is one the most important contamination index for air quality monitoring. This article presented a new PM10 concentration analysis approach based on a quick atomospher correction (QUAC) model and support vector machines reggression (SVR). The deriviation of six MODIS bands before and after QUAC model is calculated as indicating...
