PURPOSE: A seacoast guard system is provided to easily detect the small-sized submarine, infiltrated into the coast, at a guard post, and automatically cause the infiltrated submarine to make a navigation difficult or have a navigation accident by limiting an active sonar operation in the submarine for sensing obstacles so that a defence corps stationed in land can immediately concentrate fire at the detected point. CONSTITUTION: A guard system comprises sonars(1) at least more than two, a plurality of connection cables(2), a plurality of network matching devices(3), an army communication network(4), and an alarm generator(6). The sonars(1) fixed on an upper front of a main body(7) are installed at area of high infiltration possibility in the seacoast and operated in active or passive mode. The cables(2), installed under the sea, transmits the sonar detected signals to the army network(4) via the matching devices(3). The army network(4) determines if the submarine infiltrates into the seacoast or not, and generates control signals for the alarm generator(6) to let the post guars know the state of the submarine infiltration.
