摘要： PROBLEM TO BE SOLVED: To provide a maritime monitoring/searching method capable of quickly grasping the situation of sea area in the sea surface to be searched and efficiently monitoring or searching an object. SOLUTION: Laser light 23 having rectangular shape with a predetermined ratio is applied from a laser radar 22 mounted on a flying airplane 21 (fixed wing or rotary wing) at high speed to the sea area 10 to be searched where an object 11 is supposed to exist to acquire the imaging information of the imaging area 24 (laser applied area) which is acquired at one time in the sea area 10 to be searched. The information for the wave in the sea area 10 to be searched is acquired from the imaging information. A searching depression angle (θ) of the laser radar is determined from the acquired information of the wave in the searched sea area 10 to search the object 11. COPYRIGHT: (C)2010,JPO&INPIT
