Application of time sequence phased weighting method for low cost BeiDou anti-jamming antenna array

To design a miniaturized low cost anti-jamming BeiDou antenna array system, the time sequence phase weighting (TSPW) technique is used to reduce the use of RF channel. In comparison with other methods to realize the single channel structure, TSPW has a lower hardware requirement and cost. In this paper, a four-element BeiDou navigation array using TSPW is simulated. By applying the power inversion (PI) algorithm, the jamming impinging at the antenna array can be suppressed. Furthermore, the investigation of the time delay caused by the reduction of hardware is given. The simulation results show a good performance when TSPW method is applied in stationary jamming cases. However, the performance is deteriorated in the non-stationary jamming case due to the time delay of the TSPW method.
