In the development of ocean dynamics, nonlinear partial differential equations have important applications. Dynamic equation can be divided into continuous equation and pulse equation, the general dynamic equation including the form's equation, form equation flushing, jagged periodic impulsive equation, step frequency pulse equation, linear frequency modulation equation, nonlinear frequency modulation, phase coded equation, etc., here introduces commonly used equation of linear frequency modulation, nonlinear frequency modulation, phase coded equation, etc. In order to further improve the processing capacity of the dynamic equation, on the basis of the detailed analysis of the nonlinear partial differential model algorithm, the Mat lab tool was used to realize the simulation verification of the algorithm model. The principles of pulse pressure, MTI, MTD, CFAR, ranging, velocity measurement and Angle measurement were analyzed and elaborated.
