Analysis of Shared-frequency Interference among Surveillance Radars in Ship Formation

This paper adopts a method based on interference-to-noise ratio(INR) and interference accumulation time probability to analyze and study the shared-frequency interference among the surveillance radars of different ships in ship formation,synthetically considers many characteristics of electromagnetic interference(EMI) in frequency domain,time domain,space domain and intensity,etc.in the process of building the mathematics model,and fetches the primary conclusion by analyzing a practical example,which can present technical support for the electromagnetic compatibility(EMC) research in the ship formation.
