| One of the developing trends about marine navigation radar is the adoption of computers such as embedded processor and digital signal processor. Compared with traditional radar systems, embedded radar system is smaller., more stable and easier in operating. With the background of persistent ascend in performance and descend in price of semiconductor products, this paper describes the design and implementation of a marine navigation radar system based on embedded processor and digital signal processor.Chapter one discusses the development trend of marine navigation radar, embedded system and DSP technology.Chapter two introduces the principle of impulse radar and the digital information acquires method of embedded radar, including the sampling of echo and the acquisition of angle.Chapter three presents embedded system and DSP technology, including their character, developing state, development method and tools.Chapter four discusses the functional layout of the system and than provides the system's total architecture and the detailed architecture design of the lower unit.Chapter five discusses the software design and implementation of the DSP sub system. The architecture, algorithms, implementation and optimization are included. Also discusses the communicating method adopted in the communication between DSP and the embedded processor.Chapter six draws a conclusion of this paper and make a forward looking on the expansion of the system's performance and function. |
