碩士 === 國立臺灣海洋大學 === 電機工程學系 === 101 === Radar systems has the best telemetry capability before the manufacture of satellite in the 20th century. With rapid advances in semiconductor industry and development, radar systems gradually military use spread to common use in recent years. Its applications include detect large metal objects initially, weather observation, ground-penetrating exploration and physiological telemetry systems, etc. Miniaturized radar systems , system integration and innovative application are important issue of future development, so this thesis builds a radar system that can support a variety of measurement requirements and different display platform. We propose the concept of using cloud technology for multi-style telemetry radar system, analysis and design of data with pulsed radar system. And use FURUNO FR-8122 radar system (FR-8122 radar system use for waves probe at NTOU: Department of Marine Environmental Informatics) to system verification. FURUNO FR-8122 radar system within the four types of original signal, including Video, Trigger / sync, Heading and Bearing. This project establishes the signal source and capture device with the four original signal and AlazarTech’s ATS9440 14 Bit precision ADC capture card, and with Visual Studio C # to filter the original signal and mapping radar system chart. Most streamlined way to preserve valid signal integrity, saving Video as polar coordinate array, and then converted to Cartesian arrays from polar coordinates array via the coordinate and space linear interpolation. Storage draw the radar system chart, simulated radar system display, designed to change parameters such as range, GAIN, A/C RAIN, A/C SEA ... and other settings to meet a variety of measurement requirements. Most modern radar systems telemetry only for a single project, there is not making full use of radar systems capabilities. A contribution of this thesis saved the original signal, and then follow the measurement requirements with various parameters, thereby showing different radar chart, and stored it with the Cartesian coordinate array in the cloud sharing. Users receive data that can‘t be limited by to locations and platforms, can see real-time radar anytime. It also can be integrated electronic navigational charts, weather maps and other information to make more accurate ... use.
