Modulation Linearization Technique for FM/CW SAR Image Processing Using Range Migration

open access: yesApplied Sciences, 2021
Linear FMCW radar suffers from impairments in range and range rate if there are errors in the modulation rate or phase discontinuities. Often, this is a result of a nonlinearity of the voltage-controlled oscillator that is in the source of the transmit ...
