It is composed of 2 radars: the UHF Ultra and the S band SPECTRA. TERRA's performance is achieved through automatic handover and redundancy between the ULTRA and SPECTRA radars, combined with improved target load sharing, Electronic counter-countermeasures (ECCM) and severe-weather resilience.[1] The system can be used for ballistic missiles and space objects detection and tracking at very long ranges.[2] Both Spectra and Ultra are active electronically scanned array (AESA) radars that are made up of thousands of transmit/receive modules and use gallium nitride technology (GaN) to enhance their efficiency.[3] See also
