  • 摘要: 傳統(tǒng)頻率分集陣列雷達(dá)在水平陣元間引入線性頻率偏差，其波束在方位維與距離維具有耦合性，且存在柵瓣。針對此問題，該文提出一種基于俯仰頻率分集技術(shù)的波束形成方法。首先建立俯仰頻率分集陣列雷達(dá)信號模型，詳細(xì)分析了發(fā)射方向圖的時間依賴性和柵瓣特性。然后通過設(shè)計(jì)接收端的陣元參數(shù)，合成無柵瓣的發(fā)射-接收方向圖。仿真實(shí)驗(yàn)驗(yàn)證了所提方法的有效性，所得波束在距離維與方位維無耦合，且主瓣寬度較窄。
    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.
