Modeling And Simulation Of Multifunctional Three-dimensional Radar System

As a multi-function and high-performance radar system, multifunctionalthree-dimensional radar system has the advantages of flexible beam pointing direction,versatile waveforms, as well as powerful data processing capacity. It is playing animportant role in the future advanced radar system. Modeling, simulating and analyzingthe performance of multifunctional three-dimensional radar system by simulationmethod has become an important research filed now.This paper introduces a design scheme and realization flow of multifunctionalthree-dimensional radar simulation system, based on MATLAB/SIMULINK andVisual C++platform. According to the scheme, the system includes transmitter model,target model, echo model, receiver model, signal processing model, data processingmodel and resource scheduling model. The working mode of the system haslow-altitude detection and high-altitude detection. Because of these two differentworking modes, two different methods of altitude measurement had been studied in thispaper. The system uses a phased array antenna to achieve the task of search,confirmation, tracking and tracking losing treatment of high-altitude targets andlow-altitude targets. Finally, the multifunctional three-dimensional radar system isconstructed and simulated. Simulation results validate the correctness of the abovesystem.
