Hybrid simulation method to analyse anti-jamming receiver

Interference and anti-jamming of communication systems are key areas of electromagnetic compatibility research. Because of the restrictions of the complexity of communications systems, it is difficult to accurate analyze system characteristics by model and simulation. This paper presents a hybrid simulation method (a digital behavioral simulation and in-the-loop simulation analysis) to simulate effects of anti-jamming receiver. After achieving an accurate model of receiver, we realized analysis of the additive narrowband interference, additive modulation interference and band selective. Practice proved that the hybrid simulation method is accurate. It can achieve rapid analysis and verification for an unknown communication system.
