Abstract: In order to improve the efficiency of radar data processing, a software platform for radar data processing is designed and implemented based on visualization technology. The design of two core components of the platform, namely, the waveform chart and the text window, is emphasized. The waveform chart is used for the observation of data as a whole as well as in detail. The operations imposed on the waveform curve include panning freely, scaling horizontally or vertically, viewing data point, etc. And the waveform chart data can be dynamically selected based on a proposed data selection algorithm. An alternate visualization method of viewing and processing data lies in the design of the text window where a shortcut menu is utilized to enhance the interactivity of the human-computer operation. A fast and efficient drawing algorithm is adopted to improve the drawing speeds of both the waveform chart and the text window. The application results of data processing for a certain type of monopulse radar show that using this software platform improves the data processing efficiency.
