ASELSAN has teased ALP 400-G, ALP 150-G/P, and ALP 600-G radars to join the Steel Dome integrated air defence system in TEKNOFEST 2024.
The newly shown radars include ALP 400-G searching radar and ALP 150-G/P radar alongside a clearer image of ALP 600-G high-altitude radar.
Judging from the layout, ALP 400-G might be a long-range searching radar operating at lower frequencies (or longer wavelengths) than ALP 300-G. Low frequency provides advantages against targets with RCS reduction measures but is considerably more inaccurate than higher frequencies.
As ALP 300-G operates in the S-band, ALP 400-G's band is likely within the boundaries of VHF and S bands.
To combat accuracy problems, ALP 400-G could be paired with ALP 300-G and other long-range radars operating in shorter wavelengths.
ALP 600-G or YİRAD (Abbreviation for High-Altitude Radar in Turkish) will be a major component in Early Warning and Ballistic Missile Defence (BMD) capabilities with a range beyond that of ALP 300-G (ERALP) and ALP 500-G (Larger fixed version of ERALP). The radar will likely work in conjunction with the Siper Product 3 long-range air defence missile, which can intercept cruise missiles.
ALP 150-G/P mounted on a trailer has a rather unique antenna. Upon inspection of other radars with a similar antenna layout, ALP 150-G/P might be a passive radar. Furthermore, P likely stands for passive in the radar's ASELSAN designation. ASELSAN is known for its projects in the passive radar field. Passive radars detect and classify emissions from the target's radar instead of sending and receiving signals. For this reason, they are regarded among the possible solutions against low-observable aircraft like F-35, Su-57, and J-20. The lack of a transmitter also renders them invisible to anti-radiation missiles, which rank among the top threats against radars.
KORAL electronic warfare system has also been shown within the Çelik Kubbe (Steel Dome) system, which can receive and classify signals or perform electronic attacks.
