Radar system and method of due regard/detect and avoid sensing and weather sensing

摘要

A radar system and a method can utilize a radar antenna, such as, an active electronically scanned array antenna. The radar system can include a processor configured to scan a volume of space via the radar antenna to detect aircraft threats and to detect weather threats. The processing system can utilize a first pattern to detect the aircraft threats or obstacles and a second pattern to detect the weather threats.

1. A method of using an airborne radar, the method comprising:
providing a first radar pulse pattern for weather detection simultaneously or near simultaneously at a first elevation and a second elevation using an active electronically scanned antenna array; receiving first radar returns associated with the first elevation and second radar returns associated with the second elevation using the active electronically scanned antenna array; and detecting weather using data associated with the first radar returns and the second radar returns, where errors associated with time sample differences are reduced due to the providing by the first radar pulse pattern at the first elevation and the second elevation simultaneously or near simultaneously.
