WebAug 28, 2007 · Abstract. One of the advantages of Frequency Modulated Continuous Wave (FMCW) radars is the relative low required sampling frequency even when transmitting high bandwidths. This is a consequence ... Web9.3.2 Analysis of an FMCW radar IF signal. For FMCW radar, a variety of modulations is possible. The transmitter frequency can vary up and down as follows: sine wave, sawtooth wave, triangle wave, square wave, etc. Sawtooth modulation is the most used in FMCW radars, so the following analysis is based on the sawtooth wave.
