168:, which was planned to be installed as a ship, it was found that the antennas of the AN/SPS-40 would come into contact with each other when the ships of the same type were moored in parallel. Many Yagi-style dipole arrays were arranged in a planar frame (28 in total: 4 vertical rows x 6 horizontal rows + 2 on the outermost side of each row). The antenna of the identification friend or foe (IFF) is mounted on top of it. The frequency used is considered to be ultra high frequency (UHF; P (B) band), similar to AN/SPS-40. There are three variations of OPS-11, OPS-11B, and OPS-11C. OPS-11B is an amplifier added to increase the output, and OPS-11C is solid-state based on OPS-11B and movement target indication (MTI). The technology was introduced to enhance the clutter suppression performance.

For this reason, the pulse compression technology that was originally planned to be introduced from AN/SPS-40 will be researched independently. The Maritime Self-Defense Force already had
