摘　　要：该文通过对电磁波测距的有关问题分析认为，实时测频对提高测距精度较为有利，并提出在高精度测边中应进行实时测频的观点。给出了实时测频的距离计算方法，对《规范》[1]中频率改正公式提出修正意见。对实时测频测距的精度进行了分析。By analyzing tbe problems related to the electro-magnetic wave measurement of distances, this paper holds the view point that the real time frequency measurement comparatively favors the enhancement of distance measurement precision, and also presents that the real time frequency measurement should be conducted in the high precision side measurement. It gives the distance calculating method in real time frequency measurement. It also presents amending suggestions for the frequency correction formulae in the 'Code'(1). It conducts analysis on the precision of the real time frequency and distance measurement.
