Requirement Analysis of Linearity for FMCW Source using Open-loop Correction

摘要

Recently, the effect of non-linear frequency modulation to resolution is clearly analysed, but it is still didfficult to determine the proper requirement of FM linearity according to expected range resolution so that system is implemented in satisfactory performance and moderate cost. To solve this problem, we build model of FMCW soruce under corrected conditions and analyse the relationship between linearity and resolution using Monto-Calo method based on this model.
