现代船舶导航雷达利用微处理机进行数据处理,使船舶导航自动化进入一个新的发展阶段。然而,雷达杂波却严量地影响着这类设备的优越性的发挥,该问题至今未能得别完善解决。本文提出对船舶导航雷达的各种杂波进行频段分集、极化分集、脉宽分集、波束分集和扫描相关的综合解相关处理方法。它与恒虚警处理方法相比较,可避免恒虚警损失之缺点;与单一解相关方法相比较,可克服适应条件的局限性。文中逐一论述了各种解相关方法的原理后,提出了综合解相关处理方案,分析了综合解相关处理的性能。实际计算与实验表明,此方法是可行的。
Modern ship navigation radar using microprocessor data processing, navigation automation ship into a new stage of development. However, radar clutter has a serious impact on the superiority of such equipment, which has so far failed to be completely solved. In this paper, we propose a comprehensive de-correlation method for the various clutters of ship navigation radars, including frequency band diversity, polarization diversity, pulse width diversity, beam diversity and scanning. Compared with the CFAR method, it can avoid the shortcomings of loss of constant false alarm. Compared with the single solution method, the limitation of adaptive condition can be overcome. After discussing the principle of various solution-related methods one by one, a comprehensive solution scheme is proposed and the performance of the integrated solution processing is analyzed. The actual calculation and experiment show that this method is feasible.
