[Abstract]
In this paper, a specific electronic intelligence system is selected which uses combined frequency and direction measurement system. Its coarse measuring system and fine measuring system are analyzed in terms of the intercept performance. The simulation result of front end intercept probability and intercept time are given. The result shows that if the fine measuring system is guided by the coarse measuring system, the intercept time is 1.5 to 3 seconds and intercept probability is 50%, and the intercept time is only 3.5 to 6 seconds for intercept probability of 90%.
