    Abstract: A weather radar system initiates a horizontal scan at a first tilt angle, then adjusts the tilt angle down during an intermediate phase of the horizontal scan, and finally adjust the tilt angle back to the first tilt angle for an end phase of the horizontal scan. The intermediate phase may comprise a fifteen-to-twenty-degree arc centered about a centerline of the weather radar antenna. The radar system may perform test horizontal scans at intervals within a predefined range, each having a different fixed tilt angle to identify tilt angles having desirable signal-to-noise ratio and signal-to-clutter ratio at different phases of the scan. Alternatively, the system may execute a vertical scan and at one or more horizontal positions to identify desirable tilt angles at various phases.

    Abstract: A rotatable antenna is disclosed comprising a wireless rotatable interconnect comprising: a stator coil pad, a rotor coil pad, and a radiating element coupled to the rotor coil pad. In an embodiment, changes in a rotation of the rotor coil pad about an axis change a pointing direction of the radiating element. Moreover, a first channel of a plurality of wireless channels transfers power from the stator coil pad to the rotor coil pad and a second channel of the plurality of wireless channels transfers data between the stator coil pad and the rotor coil pad. Also, a data encoder may be coupled to the rotor coil pad that modulates at least a portion of the data transmitted through the second channel of the plurality of wireless channels onto a radio frequency (RF) signal, and provides the RF signal to the radiating element.
