Abstract: Some embodiments of the invention provide Pulse Doppler Polarimetric radars that are configured in a manner to eliminate traditional components that contribute to the high system cost, the overall weight and the low reliability of the radars. In some embodiments, each radar includes a (1) a beam steering walking splash plate with positioning actuator(s), (2) a feed horn antenna with wave guide assembly, (3) a parabolic reflector, (4) radar electronic components, and (5) radome and mounting bracket(s). The feed horn antenna, parabolic reflector, and wave guide assembly (including a signal generator) are stationary with respect to each other in some embodiments.
