Final answer:
Airborne radars are able to distinguish targets from ground returns by using different radar signal processing techniques and algorithms.
Step-by-step explanation:
Airborne radars are able to distinguish targets from ground returns. This statement is True. Airborne radars are designed to detect and differentiate between various objects in the environment, including targets (such as aircraft) and ground returns (such as terrain or buildings). This is achieved through the use of different radar signal processing techniques and algorithms.
