 Polarimetry can also be included in computational analysis of waves.For example, radars often consider wave polarization in post-processing to improve the characterization of the targets.In this case, polarimetry can be used to estimate the fine texture of a material, help resolve the orientation of small structures in the target, and, when circularly-polarized antennas are used, resolve the number of bounces of the received signal (the chirality of circularly polarized waves alternates with each reflection).
