Compared to the traditional passive chaff jamming, the radiating on chaff compound jamming can enhance ability of self-defense and survival capability of fighters in battlefield. In order to study the jamming effectiveness and strategy of radiating on chaff compound jamming in countering active radar AAM, by using a typical air battle situation model, this paper, based on velocity deception condition, analyzes the advantages of compound jamming over the traditional passive chaff jamming in countering active radar AAM in frequency. The paper proposes a method of frequency modulation in cooperation with fighter's motion to greatly enhance the efficiency of compound jamming velocity deception on active radar seeker. The simulation results show that this method is efficient in velocity deception jamming, the effectiveness of this method is verified, and has a guiding role in practical air battle.
