A study to determine the theoretical feasibility of a new array beam steering technique was conducted. A uniform pulse train is fed to an array containing a fixed gradient of delay across the aperture. Electronic phase beam steering is provided by controlling the pulse-to-pulse phase of the pulse train signal. Wide bandwidth beam steering is obtained when the delay, between successive pulses is controlled. Advantages include the elimination of beam steering on a per element basis and the need for beam steering control of only one phase andor delay element in the transmit or receive array. The technique is compatible with other beam steering techniques and subarraying. The technique is effective on transmit and receive arrays. On receive, the range ambiguity inherent in a pulse burst waveform is a problem. For a planar array the requirement of beam steering by another technique, between rows, is a disadvantage. Author
