| Abstract | ||
| This paper presents the mathematical analysis of a proposed jamming technique used against IAC monopulse radar. The idea of this technique is to repeat the radar signal with change in its amplitude and phase (deception jamming signal) to produce an angular error in the target tracker. This error changes for different values of amplitude ratio and phase difference w.r.t the target signal. In the generated deceptive jamming signals, the change in the amplitude ratio makes large effect than the change in the phase difference on the real part of the complex measured error angle. The real value of the complex measured angle due to jamming with constant phase difference and different amplitude ratio has large variation at amplitude ratio less than three. This value converges to the value of the angle of the false target for higher amplitude ratio. There is no jamming effect at amplitude ratios less than one and for some values of phase difference. At these values, the measured angle equals to the angle of the real target. At least two jamming signals are required to have the complex error jamming angle to overcome the ECCM techniques that might be used by the target. | ||
