Abstract: Pulse Doppler (PD) radar has good ranging and velocity measurement performance, and it is widely used in the target detection of battlefield radar. How to effectively combat it has been the focus of research. and the existing jamming methods have obvious shortcomings in the flexible spatial distribution and controllability of two-dimensional false targets. Therefore, this paper proposes a deceptive jamming method based on template modulation for PD radar, which can obtain the jamming signal by multiplying the intercepted signal with the jamming template. The simulation results show that this method can not only effectively generate two-dimensional false targets with flexible and controllable quantity, amplitude and spatial distribution, but also realize the effect of smart noise jamming in two dimensions of distance and velocity at the same time. In addition, this method is weakly dependent on the reconnaissance parameters, and the modulation process is simple and easy to realize.
