The development of computer technology advances the modeling and the technology of simulation, which make the computer simulation develop increasingly as an independent knowledge. Due to its economy, flexibility and hign efficiency, it's used widely in many kinds of research and engineering domain. In the field of Electronic Counter Measures (ECM), the model for researching the pulse Doppler (PD) radar's system, jamming and anti-jamming is the typical application.In recent years, the modeling and simulation of PD radar's system using Matlab, SPW are implemented, with the restriction of portability, compatibility, so we adopt Microsoft VC++6.0 as the simulation language to solve these problems. The whole system consists of signal environment, receiver and signal processing and data processing, and this thesis mainly discusses the model of the first two parts.In the signal environment part, reference frame set, the echo of targets, system noise are modeled and simulated; the main forms of clutter are given. Coordinates, target parameter calculation and generation algorithm of commonly used random variables are discussed in detail, including four kinds of Swerling models. In the receiver and signal processing part, basic modules are introduced and analyzed, such as gain control, quadrature coherent detection, pulse compression, clutter processing, doppler filtering, constant false alarm rate (CFAR), range and velocity ambiguity solution, monopulse measure of angle error, and their diagrams are given. Commonly used methods of quadrature coherent detection are summarized, as well as their...
