RADAR APPARATUS ARRANGED FOR OPERATION IN METEOROLOGICAL AND/OR ATMOSPHERIC STUDIES

According to an example embodiment, , an antenna assembly (110) for a radar apparatus (100) is provided, the antenna assembly (110) comprising: a feed antenna (111) arranged to radiate outbound radio waves that represent a transmitted RF signal supplied thereto and capture a received RF signal that represents inbound radio waves received thereat; and a focusing element (112) arranged to collimate the outbound radio waves into a transmitter beam (113) for transmission towards a monitoring direction and focus inbound radio waves of a receiver beam received at the focusing element (112) from the monitoring direction for reception at the feed antenna (111), wherein the arrangement of the feed antenna (111) and the focusing element (112) is configured to transmit the transmitter beam (113) as a sequence of substantially concave radio waves (113a) and receive the receiver beam as a sequence of substantially convex radio waves.
