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.

The antenna has two distinct frequency scanning ranges between 18.0 GHz and to 37.20 GHz with Sidelobe level ≤ -10 dB. A dual Bruce array, using two-way Klopfenstein tapered feedline power divider, is ...
