Modeling And Stimulation Of Airborne Fired Control Radar System

Modeling and simulating an airborne fired control radar system, the scheme argumentation and performance evaluation of radar system are accomplished efficiency by simulation of radar system, shorten designing period, reduced development and avoided repeated work. Thus radar system can be optimum designed conveniently and efficiently.Firstly, the transmission signal and moving-target models are established, and echo model is presented, including eclipsing, clutter, the modulation of sum and subtract channel. Then radar signal processing models are modeled and simulated, and the principle of high-low filter is emphasized in detail and the calculation of the filter's coefficient is given. How to implement the mechanism of closed loop feedback of angle is introduced. Finally the system models of high pulse repeat frequency airborne fired control radar is established by using established models, the ranging function of the radar is modeled and analyzed, using different transmission signal and the method of pulse modulation. The modeled charts of ever parts are given and the results are analyzed. The average errors are achieved by simulating the measure angle, speed and rang and the precision of the radar is analyzed to verify the correctness of all the models again.The models established in this paper are hierarchy models, which are convenient to transplant and modify, and they perfect the radar system software library. They provide good foundation for simulation and application of radar system and provide preference to modeling, simulation and evaluation.
