Abstract

With the characteristics of narrow scanning beam and high spatial resolution, sparse array becames a research hotspot. However, it can produce higher side lobes which leads to the information leakage easily. A physical layer secure transmission method based on sparse array was proposed in this paper to achieve secure communications. We used the genetic algorithm with two objective functions to produce multiple sparse array structures with low sidelobes, and then created a codebook. When transmitting signals, we selected a sparse array structure randomly for each symbol from the codebook. Both theoretical analysis and simulation results show that the proposed method can ensure the communication security.
