A Transmit/Receive Array combination with high resolving power wherein the Signal Dependent Noise contributors to Image Quality, as determined by the Peak Sidelobe Ratio (PSLR) and the Integrated Sidelobe Ratio (ISLR) are controlled largely independently of the Main Lobe Width. The receiving array is comprised of a number of discrete elements, nominally at half wavelength spacing. The Receive Array is weighted to aid in the control of PSLR and ISLR. The Transmit Array is comprised of a sparse array of discrete elements (more than two). The Transmit Array is longer than the receive array. The transmit array may be weighted to aid in the control of PSLR and ISLR.
