Abstract

A phased array antenna controls its beam steering direction by phase differences between signals transmitted from multiple antenna elements. These phase differences are determined by antenna geometry and carrier frequency. Radars with phased array antennas, operating with frequency-modulated waveforms, suffer from beam steering direction errors, denoted as squint. This phenomenon and the resulting squint errors are especially significant in wide-band radars. This work proposes to utilize the nonlinear frequency-modulated Tansec waveform to compensate for the carrier frequency variation and thus, to mitigate beam squint. A method for Tansec waveforms selection is derived and its ability to mitigate beam squint is demonstrated via simulations.
