What are the types of radar polarization?

• A. Horizontal, Vertical, Circular
• B. Horizontal, Vertical, Elliptical
• C. Linear, Circular, Diagonal
• D. Polarization, Planar, Circular

Answer: (A)

Radar polarization describes the orientation of the electric field of the transmitted wave, and the common basic types are horizontal, vertical, and circular. Horizontal polarization means the electric field oscillates along a horizontal line; vertical polarization means it oscillates along a vertical line. These are examples of linear polarization, where the field stays along a single plane. Circular polarization occurs when the two orthogonal components (horizontal and vertical) have equal amplitudes and a 90-degree phase difference, causing the electric field vector to rotate in a circle as the wave propagates. This type is helpful because it is less sensitive to the orientation of a target and can improve reception under certain clutter and multipath conditions. Elliptical polarization is a broader, more general form that encompasses all intermediate states between linear and circular; it’s not commonly listed as one of the basic categories in many introductory classifications, where the emphasis is on the simple linear (horizontal or vertical) and circular states.
