摘要: A new approach to adaptive phase-only nulling with phased arrays is described. An efficient method presented synthesise directive beam and multi-beam patterns create nulls in interference direction. The proposed based on iterative minimisation of a function that incorporates constraints imposed each direction respect excitation phases neural network technique. Various results are show the advantages limitations this approach. back-propagation algorithm proves be better than previous algorithms. To verify performances technique, an eight-element array has been realised tested for various types configurations.
