| Abstract: | A parallel calibration method using PN sequences to measure carrier phase differences is proposed.The method has many advantages such as high accuracy,parallel signal processing,short required time and the same calibration channel.A test bench based on the current spread spectrum TT&C multi-function digital baseband system is established.Validation and test shows excellent agreement between the calibration method and theoretical analysis. |
