Abstract:Precision jamming is a new concept in the field of electronic warfare, of which the core idea is that to deliver jamming power to target devices through cluster drones efficiently and accurately, without affecting the normal operation of neighboring devices. However, current narrowband waveform design methods cannot accurately control the minimum synthesized power within the target area, making it difficult to implement effective interference in practice. However, the computational efficiency of existing broadband waveform design methods is relatively low. To solve the above issues, this article proposed two precise interference waveform design methods for narrowband and broadband signal models, respectively. In the narrowband waveform design method, the objective is to minimize the maximum synthetic power of the neighbor region, and the constraint condition is that the minimum synthetic power of the target region is higher than the given threshold. The waveform covariance matrix is solved by the semi-definite programming method. In the wideband waveform design method, the fourth order objective function of the waveform is first reduced to a second order, and then solved using the alternating minimization method. Simulation experiments show that the narrowband waveform design method proposed in this paper has better interference effectiveness than those existing algorithms, and the broadband waveform design method has a higher computational efficiency.
