Type segmentation of the Coast Surveillance Radar market distinguishes three primary frequency bands—X‑band, S‑band, and K‑band. X‑band radars, operating between 8 and 12 GHz, dominate short‑range harbor monitoring due to their high resolution, accounting for roughly 45 % of total market revenue. S‑band systems, spanning 2–4 GHz, balance range and resolution, making them the preferred choice for medium‑range border security and vessel traffic management, contributing about 35 % of market size. K‑band radars, above 18 GHz, offer ultra‑high resolution for specialized tasks such as oil‑spill detection and small‑craft identification, but their higher cost limits adoption to niche segments, representing approximately 20 % of the market. The distribution reflects operational trade‑offs: higher frequency yields finer detail but reduced range, influencing procurement decisions across maritime authorities and commercial operators.
