摘　　要：针对舰艇指控系统鉴定试验中,真值数据与测量数据时戳常有所差异,需要进行差值计算的现状,研究了线性插值法、三次多项式插值和三次样条插值三种差值方法,推导了三种插值方法公式,并以舰船试验鉴定中指控系统试验航路为实例,应用三种插值方法对试验数据进行处理分析,证明了三次样条差值的优势。Aiming at appraisal test of interpolation computing requirements in warship command and control system,due to truth data is different form measurement data timestamp,three interpolation methods of linear interpolation,cubic polynomial inter⁃polation and cubic spline interpolation are studied.The formulas of three interpolation methods are deduced.Taking the test route of command and control system in ship test and appraisal as an example,three interpolation methods are used to process and analyze the experimental data,which proves the advantages of cubic spline interpolation.
