Abstract:

TRAD(Towed Radar Active Decoy) becomes a most efficient way against radar-guided missile,and it plays an important role in ECM field.Two kinds of jamming style belonging to TRAD are simply recited;secondly four kinds of noise jamming model are mainly analyzed.Then,the error changing curves of the decoy is analyzed between forward jamming and noise jamming style;the paper detailed simulates and analyzes that the decoy brings in effects to the single-pulse radar seeker in four kinds of noise jamming model,and assesses the jamming effect.

Key words: TRAD;forward jamming;noise jamming
