Abstract: The present invention is a method for providing hazard alerting for an aircraft via an airborne weather radar system. The method includes performing multiple weather radar scans at various tilt angles via the system and receiving radar returns via a receiver. The returns are stored in a memory of the system and merged with ground clutter suppression algorithms for eliminating ground returns from the stored returns and for creating a weather image based on remaining returns included in the stored returns. The image is provided via a weather radar display of the system, and includes an alert icon and an alert message when a hazard is present within an area proximal to the aircraft and is at or above a severity level threshold. The alert icon and alert message collectively indicate a type, severity level and location of the hazard in azimuth relative to a heading of the aircraft.

Abstract: A radar system is disclosed. The radar system comprises an antenna mounting apparatus coupled to the aircraft, and an antenna rotatably coupled to the mounting apparatus. The antenna is configured to rotationally orientate for an azimuth scan and electronically orientate for a tilt scan.

Abstract: A rotary joint is disclosed. The rotary joint comprise a power transfer interface for transferring power between a first portion having a first magnetic core and a second portion having a second magnetic core and rotatable relative to the first portion. The rotary joint may also comprise a data interface for transferring data between a cable and a second cable that is rotatable relative to the first cable.
