Abstract

A radar altimeter is described herein comprising a transmitting antenna (11) and a receiving antenna (12), wherein said transmitting antenna is configured to transmit a first radio frequency "RF" signal (13) and wherein said first RF signal (13) is configured to be reflected back to said radar altimeter as a second, corresponding reflected signal (14). The receiving antenna (12) is configured to receive said second, corresponding reflected signal (14). The radar altimeter further comprises an antenna radome (60) provided relative to said transmitting antenna (11) and said receiving antenna (12) such that said first RF signal (13) passes through said radome (60) after being transmitted from said transmitting antenna (11) and wherein said second, reflected RF signal passes through said FSS radome before being received by said receiving antenna (12). The radome comprises a frequency selective surface "FSS" antenna radome (60).
