Radar waves have a polarization. Different materials reflect radar waves with different intensities, but anisotropic materials such as grass often reflect different polarizations with different intensities. Some materials will also convert one polarization into another. By emitting a mixture of polarizations and using receiving antennas with a specific polarization, several images can be collecte… WebAug 19, 2024 · Using a chirped pulse provides more information in that it can be used to determine range and velocity from multiple targets simultaneously. 1 or 4 GHz linear chirp is typically used in 77 GHz automotive radar systems, which makes data processing easier while still providing accuracy that is comparable to exponential chirp.
