Mode of dual polarization: phased array versus parabolic dish

This paper does not present any novel material whatsoever. Instead, it provides a succinct summary of the pros and cons induced by the modes of dual polarization and contrasts the differences for the two types of radar systems: (1) mechanically steered parabolic dish, such as in weather surveillance radar 1988 Doppler (WSR-88D) and (2) electronically scanned phased array radar (PAR). Our goal is to highlight that PAR has a different set of pros and cons associated with its dual polarization capability compared to that of WSR-88D. The paper discusses why a certain mode of dual polarization on WSR-88D was chosen in the past, and explains how this choice might be different on PAR in the future.
