碩士 === 國立臺灣大學 === 電信工程學研究所 === 89 === ABSTRACT
We analyze the performance of frequency hopping systems incurred by jamming for military used. In addition to the jamming model , we analyze those jamming models which have not been studied by simulation.
We introduce the typical jamming model and its performance and analyze regarding the signal characteristic of movable tone jamming and discuss the simulation model of typical frequency hopping systems. Suppose the PN code is perfectly synchronized,we use the equivalent model of typical frequency hopping system and the jamming on off model for increasing simulation speed. In order to realize the system, we use non ideal band pass filter in simulation and introduced Parks-McClellan algorithm applied by FIR filter. We find the optimal sweeping speed of chirp jamming under various signal to jamming ratios to reach the best jamming performance by simulation.
