Optimization of waveforms for UWB circular and disk antenna arrays

The basic pulse waveform is an important factor that affects the angular resolution of UltraWideBand (UWB) antenna array. The optimization of these basic pulse waveform for circular and disk array is considered; the optimization problem can be simplified and translated into a simple form, which can be solved effectively. Several optimized waveforms are given, and the main lobes of energy pattern of these optimized waveforms are much narrower than those of corresponding Gaussian waveforms. Numerical results show that optimized waveforms achieve considerable improvement in angular resolution.
