For example, a polarization controller may be configured to control a polarization for an antenna. For example, the polarization controller may include a processor, which may be configured to process interference information to identify angle-based information. For example, the angle-based information may be based on an angle of an interferer signal relative to a boresight of the antenna. For example, the processor may be configured to determine a polarization setting of the antenna based on the angle-based information. For example, the polarization controller may include an output to provide a control output to control the polarization for the antenna based on the polarization setting.

A discrete wireless miniature non-imaging millimeter wave radar sensors scanning device that detects concealed weapons hidden under humans clothing. The detection sensors include a scanning device integrated with a miniature millimeter wave radar, and an AI MM-wave laser beam camera with diffractive reflector optical lens, by converting radio waves imagery of concealed weapons from the field of view to a recording medium. The wireless miniature non-imaging millimeter wave radar sensors device works in conjunction with the AI MM-wave laser beam camera, which works as a countermeasure against laser jamming. The AI Laser camera automatically activates the built-in-polarization system when it detects radar jamming and changes the polarization light waves passing through the millimeter diffractive optical lenes.
