Abstract

An array antenna signal simulator based on VFD filter is presented. To offer the design structure and make delay control more flexible, the VFD filter, which is suitable for changing the delay time, is used to control the delay of different channels. To improve the group delay precision of VFD filter, a design method in group delay minimax sense is proposed, instead of the variable frequency response criterion. The experimental results indicate that, in the DOA simulation, the elevation simulation accuracy of the new designed array simulator is better than 2°, the azimuth simulation accuracy is better than 1°.
