摘　　要：针对两点多段线性校正法校正因子推导过于简单的缺点,提出一种改进算法。这种算法对增益系数和偏移系数重新进行推导,弥补了两点多段校正法中由于校正因子推导带来结果值偏大的不足,并对算法进行了仿真。According to the disadvantage of simple reason in the two-point multi-section correction method,a new improved algorithm is presented。Gain coefficient and deviation coefficient are infrared again in the algorithm,and offset the defect caused by two-point multi-section correction coefficient inference that lead to higher results than those obtained by other algorithms.It is shown great efficiency by simulations.
