Title    PowerPC Programming in Multi-channel   Radar Target Echo Simulator                                                    

Abstract With the rapid development of information technology and electronic technology, the radar’s performance continues to improve, so developing advanced radar is one of the most important tasks of national defense for each country. In order to overcome the outfield experiment waste of manpower and financial resources as well as some bad circumstances not feasibility of outfield experiments, it comes the radar target simulator.

  This paper first discusses the research background and meaning of the radar simulator and specific tasks and functions of the radar simulator. And then it provides an analysis of radar target track, the echo model and simulation of MATLAB. Then it introduces the PowerPC and the exchange of data between the FPGA and controller and the corresponding verification by experiments. Besides that, it derives the PowerPC-based echo signal parameters such as phase, delay and frequency control and calculation formula. Finally it elaborates the control communication between PowerPC and Real-time control computer and the corresponding verification by experiments.
