Modeling And Simulation On Shipborne Multi-Function Phased Array Radar

Shipborne multi-function phased array radar plays a vital role in warship defense system.As one of the major detection equipments of the warship,shipborne multi-function phased array radar,with functions such as searching,identification,tracking,guidance and detection,can simultaneously monitor and track multiple targets,and enjoys good anti-jamming performance and high reliability.By the signal level modeling and simulation,its performance can be evaluated comprehensively to provide the basis for the equipment demonstration.The thesis firstly clarified the mission of the shipborne multi-function phased array radar simulation system,using track and search as the scheduling mode,and proposed the overall design scheme.The overall process of simulation was described macroscopically,and the modules were divided into modules according to the idea of componentization.Then,the components of the shipborne multi-function phased array radar simulation system were modeled,which included the model of resource schedule,transmitter,coordinate transformation,target echo,active disturbance,sea clutter,receiver,signal processor and data processor.Finally,combined with the above theoretical content,the simulation system was implemented in software.With the help of graphical software,this thesis built a typical combat scene and assigned a specific track and combat mission to each target.The data required for each indicator was collected by simulation experiments,and the detection accuracy,detection factor,improvement factor,maximum radar range,multi-target tracking capability,sidestream cancellation anti-jamming performance of shipborne multi-function phased array radar simulation system were carried out by drawing and tabulation.The shipborne multi-function phased array radar simulation system built in this thesis is a hierarchical simulation system,which is Modular modeled and provides a good portability.It could lay a good foundation for the simulation and application of shipborne phased array radar,which is of referential significance in engineering.
