摘要
指出影响高频多普勒计程仪测速精度的主要因素,提出了在软件方面进行航速补偿的2种措施,通过图表分析,给出了航速线性补偿及非线性补偿2种方案。重点分析了航速非线性补偿,并给出了航速非线性补偿的软件流程框图,对提高测速精度具有较高实用意义。
Main factors which influence speed measurement precision are point out. Two measures of speed compensation from software side are presented, two ship speed compensation schemes, speed linear compensation and speed non-linear compensation, are given by chart analysis. The ship speed non-linear compensation is specially analyzed and its software design flowchart is given, which has practical values for enhancing the precision of ship speed measurement.
