The invention belongs to the water area monitoring technology field and especially relates to a water area monitoring multielement combination perception system. The system comprises an AIS data processing module, a radar data processing module, a photoelectric guiding module, an integration processing module, a multi-target fusion management module, a target integration display module and a power supply module. In the system, fusion of radar data and AIS data can be realized, and data of radar equipment, AIS equipment and camera equipment is associated. In the invention, through an integrated design of a radar and photoelectricity, the system can carry out concentration display on target information so that the radar and the photoelectricity form an organic integral body. Because of a specific composition structure of each module, a signal acquisition speed and a data transmission speed of the system are greatly increased.
