多模式下高转速船用导航雷达回波显示

由于船用导航雷达海上导航的特殊性,显控终端有不同的运动显示模式。根据实际情况,在不同运动模式间切换具有重要的现实意义。提出并构建了二维坐标变换数据表,对船用导航雷达的不同运动模式建立统一模型,实现了高转速雷达回波的实时显示。当运动模式发生变化和偏心时,均无需动态更新数据表。此方法降低了雷达实时回波显示对计算机性能的要求,具有很好的实用性。实验证明本方法在雷达转速高达48 r/min情况下,具有很好的实时性,满足工程上的需要。

The realization of echo displaying for marine navigation radar under high-rotating speed and multiple operating modes

The echo displaying of the marine navigation radar has different patterns due to the particularity of marine navigation. It is significant to switch on different displaying modes according to the actual circumstances. The real-time echo displaying of high-speed radar is realized with the construction of a two-dimensional transforming data table. There is no need to update the data table dynamically when the moving mode changes or becomes eccentric by establishing a uniform model for different moving patterns. This method reduces the requirement for high-performance of computer. Our experiments also show that this method exhibits good real-time performances under radar rotating speed up to 48 r/min, satisfying the needs of practice.
