Analysis of Time-Hopping Sequences Modulated UWB Orthogonal Hermite Pulse-Sequence Radar Signal
|
Abstract:
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 autocor...
