An Integrated System of Digital Video Capturing System, Gps and Gis for Radar Clutter Analysis

Radar clutter is very complicated signal, because it is a kind of random process and invisible to human. As a result, besides instrumental parameters, environmental parameters will play a critical role in later data analyses. At present, the research about radar clutter has become a special field, which greatly affects the development and application of radar. This paper presents an innovative and creative method to support this research. It makes use of 3S (RS, GPS, GIS) integrated technique to provide visual background information for radar signal processing. This paper proposes several applicative solutions, which can be used to realize 3S integrated system. Its opinion and method about multi-sensor cooperation lay a foundation for 3S data integration. It implements a kind of video capture system in Visual C++6.0 and video for window (VFW) technology. It is used in vehicle-borne experiment and solves the problem about automatically recording captured video. It also implements reading position data from GPS and synchronizing the three kinds of equipments (camera, GPS and radar). In addition, an algorithm is given to calculate coordinates of the radar antenna and video camera or the ground center of radar echo and the image according to coordinates of GPS antenna on airplane or vehicle.
