A standard linear array (SLA) is a [[uniform linear array]] (ULA) of interconnected transducer elements, e.g. microphones or antennas, where the individual elements are arranged in a straight line spaced at one half of the smallest wavelength of the intended signal to be received and/or transmitted. Therefore, an SLA is a subset of the ULA category. The reason for this spacing is that it prevents [[grating lobes]] in the [[visible region]] of the array.<ref>{{cite book |last1=Van Trees |first1=H.L. |title=Optimum Array Processing |page=51}}</ref>
