Networking navigation radar target tracking system based on data fusion

Abstract

The invention discloses a networking navigation radar target tracking system based on data fusion. The system comprises at least one radar front end, at least one radar terminal and an Ethernet. The radar front end and the radar terminal are in bidirectional data transmission through the Ethernet. The radar front end comprises an antenna, a transceiver, a data acquisition module, a signal preprocessor module and a control command processing module. The radar terminal comprises a display unit, a signal processing unit and a control unit. The transceiver generates radio-frequency pulses which are radiated to the space through an antenna. The system belongs to a trace point serial processing centralized data fusion structure, has the features of high fusion precision and small system time delay, and meanwhile, has the advantages of eliminating detection blind areas, improving detection probability and improving tracking performance. After the terminal carries out data fusion and comprehensive optimization processing on the data of the plurality of front ends, the problem of blind area of the single radar due to antenna erection location can be effectively solved, marine target detection and tracking accuracy performance is improved, and navigation safety is guaranteed.

Description

technical field [0001] The patent of the present invention relates to the technical field of multi-sensor data fusion, specifically, a networked navigation radar target tracking system based on data fusion. Background technique [0002] Marine navigation radar is mainly used for detection and tracking of sea targets, assisting ship navigation and collision avoidance, and ensuring navigation safety. With the increasing complexity of the ship's navigation environment, the performance of navigation radar is directly related to the safety of the ship's navigation and the safety of the people on board. [0003] Marine navigation radar is generally divided into two parts: radar front-end and radar terminal. The radar front-end includes antenna, transceiver and signal preprocessing unit, which realizes the transmission and reception of high-frequency electromagnetic waves, and preprocesses the received electromagnetic wave signals. Through clustering algorithm Detect the target an...
