Research on Simulation Techniques of Phased Array Radar

Phased array radar is a bulky and complex system.By carrying through its function decomposition and synchronization,we can turn it into mathematic model and change into simulation model which is suit to computer simulation,then carry on the simulation and verification.On the premise of that simulation precision is not affected,by predigesting it properly and substituting equivalently,blocking structure of simulating system is founded and the collectively simulation procedure is discussed.Several simulating methods about modelling are discussed and compared for advantage and disadvantage.The simulating ways of density-weighted antenna is brought forward.The researching status of the credibility of models is also indroduced as well as popular simulation techniques and emphasis.
