摘　　要：连续波雷达由于电路非线性、馈线长度等因素,使得连续波雷达测距出现一定的系统误差,这个由系统本身引起的附加距离称为零距离,雷达在投入使用前必须对该参数进行标校。文中提出了一种适用于多频连续波雷达的零距离标校新算法,并详细推导了算池过程,并详细推导了这一过程给出了相应的结论。采用该算法可以方便地测量多频连续波雷达系统的零距离,提高雷达系统的测距精度,减小测距的系统误差。The ranging results of CW radar have some system errors because of some factors such as circuits＇ nonlinearity, length of feedback ,etc. The additional range caused by system is called zero range. The calibration of this parameter must be done before the radar is put into service. A new algorithm for the calibration of zero range in multiple frequency CW radar is presented in this paper,the derivation is given in details,corresponding conclusions are also drawn. Using this algorithm,the zero range in CW radar can be measured conveniently with range accuracy improved and range system errors decreased.
