导航雷达广泛应用于舰船海面搜索与导航。它具有较窄的方位波束宽度(小于1°),小的脉冲宽度(小于0.1μs,即距离分辨力优于15m)。其显示器有A式幅度显示器与PPI平面显示器。PPI平面显示的海面景象分辨力适中,适于研究海面风场、海浪、海流,配之目标特征研究和测量技术,可进行海冰分类等工作。
Navigation radar is widely used in ship sea search and navigation. It has a narrower azimuth beamwidth (less than 1 °) and a small pulse width (less than 0.1μs, ie a distance resolution better than 15 m). The monitor has A-type amplitude display and PPI flat panel display. The resolution of the sea surface displayed by the PPI plane is moderate, which is suitable for the research on sea surface winds, waves, currents and target features and the measurement techniques, and the classification of sea ice.
