| Marine radar integrated display terminal is an important part of the radar system. Its main tasks include:radar raw data processing, target and related information display, radar state control. The main task of this research is to design the radar display system, including radar display interface design, target state information display and control the working status of radar, radar video display and moving target signal display, and also demonstrate the interface design.Firstly this thesis introduces the marine radar integrated display terminal's development status, and discusses the structure of the radar display and interface designing principles. On this basis in the Windows environment programming with VC++6.0 is accomplished a marine radar integrated display terminal's interface design and display. At the same time on the computer to complete the original radar zoom and rotate video signal, and superimpose electronic bearing lines and the range ring marks and the display of its versatility on the basis of the original video signal to adapt to the future and scalability requirements of the development.This theis gives the accurate principle objective of the motion vector calculation, including calculation principle of relative motion of the moving targets course and calculation principle of speed of true motion vector conversion, analyzes the calculation principles of the relative movement of the ship under the radar to switchover and algorithms. The main function of the radar trial maneuvering for the ship's is to prevent collisions at sea. For the conviience of risk targets judgments, we use the calculated risk of collision prediction triangle parameters DCPA and TCPA. At the same time under the platform based on Windows VC++6.0 application development tools, the true target motion and relative motion involved in the process of motion vector algorithm is accomplished, marine radar interface in normal state and off-centre state is implemented respectively. |
