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