Alternative approach to designing array pattern with controlled mean-square sidelobe level

A more general and efficient approach for designing array patterns with a controlled mean-square sidelobe level is presented. It is shown that the approach presented by Ng (see ibid., vol.26, p.337-9, 1990) can be considered as a limiting solution to the quadratic constrained optimisation problem presented in this Letter. Numerical results showed that under high interference-to-white noise ratio conditions, the new approach performs better, on average, than the Chebyshev synthesis technique.
