Since the introduction of native QR code scanning in smartphones, 2D barcodes have become the preferred method of sharing ...

Abstract: A novel direction-finding method with time-modulated array (TMA) is proposed for modulating the echo linear frequency modulation (LFM) signal and analyzing its harmonic characteristics.

Abstract: An efficient mathematical method is developed to design a time-modulated linear array (TMLA) with desired sidelobe and sideband levels with maximum achievable directivity. The array factor ...
