Design And Implementation Of PPI In Coastal Defense Radar Simulation System

A new type of sea reconnaissance radar is an important equipment of the coastal defense force,serving for the sea guard duty all the year.Because of the higher cost of the radar equipment,full use of radar training will seriously affect the radar's life and the combat duty.Therefore,the development of coast defense radar simulation system take the place of the actual radar as the training equipment is very necessary.This paper focuses on the PPI of the training system.In the simulation of tuning function,establish mathematical model,which is more realistic than real radar tuning transform.The matrix fusion method is proposed to realize the radar afterglow effect,and the intensity of any one dimensional color vector in the bitmap is controlled by the decay matrix.In this paper,the interference is studied,and the interference model is constructed for a certain type of radar.The data derived from the interference source,its variables include distance,power and lobed shape of the antenna.The antenna gain model is established.As an important module of coast defense radar simulation,target simulation resulting from the data to the target reduction,this paper the were introduced in detail.Aiming at the problem of reduction of target,the method of slice object reduction is proposed,which effectively solves the problem of PPI display.In terms of target detection,the detection method is proposed.The moving speed and direction of the target are calculated according to the identified target moving track,and the moving intention of the target is predicted according to the information of the target.This system has been devoted to the coastal radar stations,as a radar operator training platform,so as to improve the technical level of the radar operator,and contribute to the national defense science and technology.
