Optimization-based design of innovative grating-lobe free radar UWB architectures

Abstract : An innovative approach for reducing grating lobes appearing when the inter-element spacing of an UWB linear array is greater than half-wavelength is presented. The main innovation of the proposed new design methodology is related to the fact that the positions of the array elements are left unchanged in the direction of the axis of the array (thus not affecting the gain of the pattern), while they are optimized along broadside direction. Selected numerical results validate the proposed methodology.
