JEM modeling and measurement for radar target identification 总被引:2,自引:0,他引:2
The jet engine modulation (JEM) phenomenon, observed in radar returns from the rotating structure of jet engines, has been successfully exploited for aircraft target identification in a number of experimental radar systems. The authors develop a parametric model based on the periodic modulation of the scattered return, motivated by the potential reduction in time-on-target for reliable target identification provided by parametric models as well as by gaining insight into the JEM phenomenon. They compare the model with JEM measurements made with an experimental radar system and discuss the implications for JEM-based target identification systems 相似文献
