  • An ultra-wideband orthogonal Hermite pulse is an appropriate family of pulses that can represent the commonly-used waveforms in through-the-wall surveillance radar. It has advantages of flexible design,high spectrum utilization and simple design. An analytical expression of the ambiguity function for a train of Time-hopping Modulated Ultra-WideBand (TM-UWB) Hermite waveforms is derived. The relation of resolution,side-lobe suppression characteristic and unambiguous for TM-UWB impulse waveforms with the autocorrelation properties, period of time-hopping sequences, and the average pulse repetition period, order number and scaling parameter of the Hermite signal are investigated, and some application issues for through-the-wall surveillance radar,such as sidelobe suppression and clutter suppression, are also discussed.
