Abstract: Combining the analog and digital technologies,a new design method of the power-inversion adaptive array is described.Due to the new method,the performance of the system is improved while the structure is simplified.A power-inversion adaptive array system is designed and tested.Some array patterns that illustrate the anti-jamming performance of the system are obtained in the microwave anechoic chamber.An experiment is done on the adaptive array working with a GPS receiver,and the results are presented.
