Design and measurement of channel calibration for digital array with orthogonal codes

Abstract

In order to realize an accurate multi-beam forming for Digital Array Radar (DAR) system, a calibration method-the Unitary Transform Encoding (UTE)-for revising the amplitude/phase imbalance among transmitting channels is proposed. This method employs set of orthogonal codes that are sequentially applied to all channels, allowing elements to be measured in… (More)
