Guidance system using onboard radar to actively emit and receive signals for target tracking and missile course correction.

The initial propulsion phase where a high-thrust motor accelerates the missile to operational velocity.

Sea‑skimming is a low‑altitude flight profile in which a missile or projectile flies close to the sea surface to minimize radar detection and increase survivability.

A two-stage ATGM propulsion system where a booster stage initially accelerates the missile before a sustainer stage maintains flight velocity.
