👉 Acoustic missiles, also known as acoustic guided missiles or AGMs (Airborne Guided Missiles), are a type of missile that uses sound waves for navigation and guidance. These missiles emit ultrasonic pulses, typically in the range of 20 kHz to 200 kHz, which bounce off targets and return to the missile. Using a sophisticated receiver, the missile calculates the time delay and distance of these echoes to determine its position relative to the target. This allows the missile to autonomously adjust its flight path and accurately hit its intended target, even in environments where GPS signals are unavailable or unreliable. Acoustic missiles are particularly useful for anti-aircraft defense, as they can effectively engage fast-moving aircraft.
