FMCW Radar Signals Application Note Products: ı R&S®FSW ı R&S®FS-Z90 Frequency Modulated Continuous Wave (FMCW) radar signals are often used in short range surveillance, altimeters and automotive radars.

Therefore, the distance measurement accuracy of an FMCW radar is limited by the accuracy with which the value of f IF is estimated. Block diagram 17.

It will also discuss how various types of dielectric material in front of the radar antennas (e.g., antenna dome or color-coated bumper) influences the radar’s performance. It is a Frequency Modulated Continuous Wave radar in which the frequency of continuously transmitted wave is varied at a known rate and the frequency of reflected signals is compared with the frequency of transmitted signal 16.
