Airborne Pd Radar Signal Environment Simulation

In the thesis, the environment signals such as targets reflections, jamming and clutters before the receiver of the Pulse Doppler Radar are presented; the analysis, modeling and simulation of these signals are discussed.In the first chapter the Pulse Doppler Radar and Pulse Compression Radar are introduced, include their definition, working condition and specialty.The method and theory of system simulation are discussed in chapter 2. From the chapter 3 every module of the simulation is described.Chapter 3 concentrates on the modeling and simulation of antenna, and present the azimuth function and the anti-jamming technology of the antenna. The anti-jamming technology include sidelobe canceller and sidelobe blanking, the effect of these anti-jamming technology are presented also. In the chapter 4 the modeling of targets reflection signals are described, these signals consist of coherent pulse, chirp and barker sequences. In chapter 5 the jamming such as phase modulation noise, binary pseudo random sequence and multiple pseudo targets are discussed. The noise of the receiver is also described in the chapter. The modeling and computation of clutters are discussed in chapter 6.In the last chapter, the results of the simulation are presented.
