To the disadvantage exposed to us in national and foreign VTS system, and those putted up in application projects, the thesis did a farther study and consummation, and acquired some research fruits, as follows:1. Fulfilled the Eagle Eye function in Electronic Chart Display System.2. Designed a kind of simple algorithm for select chart. By this arithmetic it become true to auto select electronic chart when chart is zoomed.3. The realization of auto acquired field on electronic chart.4. The simulation of target data and error of radar and AIS by software.5. The fusion processing of the dynamic data those are collected from AIS and Radar.6. Resolve the target track problem of radar by the data fusion technology.7. The algorithm design of display field reduce, this function can improve the speed of display.
