摘要
避免海上船舶碰撞一直颇受关注,在分析比较现有船舶避碰技术的基础上,重点论述了基于DSP船舶避碰雷达的工作原理,提出了基于DSP的主从处理器的设计方案,详细介绍信号处理流程。经过软硬件实现,验证了该雷达能够检测周围障碍物的距离和相对速度,当超过门限值时能自动报警,进一步证实了此设计的可行性和实用性。
Ships collision avoidance is always attracted public attention.In this paper the technology about ships collision avoidance is discussed,and the principle of millimeter wave ships collision avoidance radar system based on DSP is described.A new design with master-slave processor based on DSP is presented and processing flow of software system are introduced,The radar can detects the nearly it immediately and gives an alarm signal when the parameters exceed the set value.All the work we have done in this paper proved the feasibility and practicability of the design.
