Abstract

Abstract

In most of the frequency diverse array radars, a small linear frequency offset is always applied across the horizontal array elements, generating a different beampattern with coupling between the azimuth dimension and range dimension. Moreover, the grating lobes also exist in the range dimension. To overcome this, a method of beamforming with the vertical frequency diverse array is proposed. Based on the radar signal model, the characteristics of the time dependence and grating lobes in the transmit pattern are analyzed. Then the transmit-receive pattern with no grating lobes is synthesized by designing the parameters of the receive elements. Simulations results show the validity of the proposed method. The synthesized pattern is range-dependent only, and also has the smaller beamwidth of the mainlobe.
