Fast Waveform Design Algorithm for Precision Interference

Precision interference is a new concept that receives widespread attention in the field of electronic warfare, which aims to avoid unexpected electromagnetic injuries to the ally''s devices in the process of electronic interference. Its core idea is to realize the precise control of interference energy in the airspace. However, the current waveform design algorithm used for precision interference has the problem of high computational complexity, which can easily delay the time of electronic warfare. Given this problem, this study proposes a fast waveform design algorithm for precision interference. The optimization problem is established according to the precision interference spatial model. The upper bound of the targeted function is derived by adopting the Majorization-Minimization framework, and the available waveform for precision interference is obtained by iteratively solving the corresponding subproblems with the closed-form solutions. Simulation experiments demonstrate that the proposed algorithm has good performance on the indicators of precision interference and the superiority of lower computational complexity.
