Abstract:

Inverse synthetic aperture radar (ISAR) is playing an important role in the military,and the research on the jamming countering ISAR has been continuously made.This paper makes a study of a coherent jamming method for countering ISAR,namely,weighted noise frequency modulated jamming.Weighted noise frequency modulated jamming can obtain some processing gain related to the conventional noise frequency modulated jamming,thus saving the jamming power.

Key words: Inverse synthetic aperture radar(ISAR);coherent interference;pre-emphasis noise FM jamming
