Abstract

Different from the conventional phased array, frequency diverse array (FDA) can provide electronic beam scanning without phase shifters and its beam steering is range-angle-dependent. Nevertheless, reported studies on FDA are most in continuous waveforms and the corresponding beampattern is time-variant, which increases difficulty in controlling the mainbeam direction and complexity of signal processing. To alleviate this problem, a pulsed-FDA is proposed with an aim to generate quasi-static beampattern in this communication. The corresponding constraint is derived together with the method to control the mainbeam direction. Moreover, the range-angle-dependent characteristics of the quasi-static transmit/receive beampattern are addressed considering the radar applications. Besides, range-angle-dependent beampattern significantly enhances the flexibility of beam scanning and its signal processing. Simulation results are in good agreement with the theoretical analysis.
