Maritime target data fusion system and method based on space-based radio monitoring

Abstract

The invention discloses a sea target data fusion system and method based on space-based radio monitoring. The system includes: a broadband receiving module, a radiation source location and measurement module, an AIS signal decoding module and a data fusion module. The broadband receiving module is used for receiving radiation source signals, and the radiation source signals include AIS signals and radar radiation source signals. The radiation source location and measurement module is used for location and parameter estimation of the radiation source. AIS signal decoding module is used to decode AIS signal to obtain AIS broadcast data; data fusion module is used to complete maritime target association and fusion, maritime target association and fusion include: AIS data association, radar radiation source data association and AIS and radar radiation Source data association. The sea target data fusion system and method based on space-based radio monitoring of the present invention realize the effective fusion of AIS radiation source and radar radiation source data, and can accurately estimate the number, position and type of sea targets.

Description

technical field [0001] The present invention relates to the technical field of maritime target detection, in particular to a maritime target data fusion system and method based on space-based radio monitoring. Background technique [0002] Automatic Identification System (AIS) is a ship target broadcast signal, which has the functions of ship tracking, collision avoidance, environmental protection and search and rescue. AIS equipment is mandatory on commercial ships over 300 tons, as well as on all passenger ships, and is also widely used on smaller ships. The traditional AIS platform is mainly shore-based AIS. With the rapid development of spaceborne AIS technology, the limited detection range of shore-based AIS has been greatly expanded. The spaceborne AIS can determine the identity and position information of the target by obtaining the AIS message sent by the cooperative ship target. However, due to illegal fishing, drug trafficking, smuggling and other reasons, the cr...

Problems solved by technology

[0003] At present, there are few studies on the perception of AIS radiation sources by space-based radio monitoring systems. Space-based radio monitoring systems lack the ability to verify the authenticity of AIS information. At the same time, they do not make full use of AIS broadcast information and radar and other radiation source positioning information. data fusion method
