Abstract
In using microwave interference to test the high-speed moving objects parameters
the noise is the key to influence the precision of data processing. On the analysis of the elementary characteristics of microwave interference signals
the methods based on wavelet transform and exact time-domain data processing are put forward to process the signals. Not only smooth testing curve is obtained but also the signal processing precision is effectively improved. In addition the methods can be used for frequency extract of other signals with high-noise and altering frequency and are of certain universality.
