| Abstract: |
| A study on the signal processing methods of time-domain measuring system is presented. Firstly, the background subtraction as a method of signal pretreatment is introduced, and FFT and CT(Chirp Transform) were applied to a time-domain UWB compact range measuring system. In the end, a comparison was made between the efficiency of FFT and that of CT. |
| Keywords: time-domain measurement signal processing chirp transform |
