Pd Radar Data Processing System Simulation

The development of computer and the technology of the simulation advances the modeling and the technology of computer simulation, which make the computer simulation as an independent knowledge develop increasingly and used widely many kinds of research. This thesis researches the data processing and the display which is the part of the testing and evaluation for the performance of PD radar's jamming and anti-jamming with simulation in the PC. The whole project finishes the integrate model for researching the PD radar's system, jamming and anti-jamming, which is the first in the domain of electronic anti-jamming in our country. The meaning is great. This thesis discusses the theory of the data processing, the display and the testing and evaluation for the performance of PD radar, establishes their math models, designs the corresponding software of simulation and shows the simulation results. In the first chapter the method and theory of system simulation are discussed and the common model of radar system's simulation are showed. In the second chapter the Pulse Doppler Radar is introduced, include its definition, clutters, working condition and specialty and the theory of measuring range and measuring velocity in radar. In addition, the flow chat of the simulation and the function of the main modules are showed. Chapter 3 concentrates on the important technology of PD radar's data processing. This chapter includes the resolution of range and velocity ambiguity and the theory of the start of tracking, the refreshment of tracking, the disappearing of tracking and the single target tracking. In the part of the refreshment of the tracking, the, the theory and realizing of the filtering algorithm and the point—tracking relating are illustrated.In the chapter 4 we amply present the specialty and of radar's display and the implementing of the radar's showing, the data's showing and the interface. In the chapter 5 we introduce the realizing of the software for rating performance of testing parameters of radar. In the last chapter, the results of the simulation are presented.The soft is achieved by the Matlab programming language and works in the PC.
