Research On The Simulation Of The Easy Configuration Satellite Interference Source

Since the1960s, satellite communication has developed rapidly and it has been very widely used in some fields. The application of satellite communication is particularly prominent. It cannot be replaced by other means of communication.The performance analysis and evaluation of satellite countermeasure system largely depends on computer simulation technology. The software simulation technology has become the mainly technical means in the process of communication system design.Analogizing real-time traffic intensity has a certain guiding significance to analyzing utilization of the limited spectrum resource and researching frequency agility technology of military communication when satellite orbits. Simulating the real-time spectrum can be regarded as an important reason in researching other key technologies of satellite communication’s system simulation platform.lt is needed to analyze the interference sources of satellite communication system and make classification processing for different variety of interference source in order to be able to more realistically simulating the satellite communication spectrum environment.The realistic interference of satellite communication system is varied. The parameters of interference can be configured arbitrarily for the purpose of being more effectively verifying the function of other parts of satellite communication system and being able to further enhance the system performance.Based on the known types of satellite communication interference source, the paper models and simulates various kinds of interference sources system and sets up various configurable parameters. According to the geographical coordinates of sub-satellite point at any time, the paper calculates the size of satellite beam coverage area and determines the types and coordinates of all geographic area in the satellite beam coverage area at any time. Based on the access and exit models of the continuous-time domain interference, the paper discussed the discrete time domain simulation of satellite interference’s the access and exit rule.The density is greatly different between densely populated areas and sparsely populated areas. And for the same area traffic intensity varies largely during the day and night. According to the number of interferences differing in different geographical areas we can model the geographic areas into different area types which own themselves traffic intensity.According to these the characteristics, the paper models the distribution of the satellite interference source in the whole satellite beam coverage and gives the parameters. Finally, the paper gives the whole interference system model and demonstrates the relevant simulation results.
