Abstract: With angle deception jamming,the angle measurement system of radar Would be intereferenced badly, and then the dangerousness of the platforms from being tracked/locked Would be decreased. On the base of the statistical analysis of measurement error about two-spot Jamming, a method of angle pull-off jamming is proposed in this paper. Only amplitude controlling is needed in this method, So it's propitious to be applicated to engineering project. Then this method is verified by system modeling and simulation, and it shows the capabilities about angle deception with this method is steady and effective.
