Abstract:

In many array radars the composite beam is di rected by quantized phase shifters. Regular sequence of quantization errors enhances side lobes and pointing errors. It is recommended to break up the regularity by small, known nonlinear and preferably quasi-random initial phase devia tions in the array elements. This reduces the lobes and pointing errors for a given number of quantization steps, especially in high gain, multi-element arrays.
