Efficient Mathematical Method to Suppress Sidelobes and Sidebands in Time-Modulated Linear Arrays

An efficient mathematical method is developed to design a time-modulated linear array (TMLA) with desired sidelobe and sideband levels with maximum achievable directivity. The array factor of the TMLA is represented in terms of a finite series of Chebyshev polynomials of the first and the third kind...
