Abstract :
A simple window that yields 6 dB improvement in the first sidelobe gain, with almost no loss in the maximum sidclobe gain, compared with that of Kaiser´s near optimum zeroth-order Bessel window, is developed. The main-lobe energy of Kaiser´s window is about 0.00078% more than that of the new window. The distinct advantage of the window is its very simple form similar to that of a Hamming window.
