Comparison of classical and orthogonal UWB waveforms for radar applications

In this paper, classical UltraWideband (UWB) waveforms and orthogonal functions (Hermite and Gegenbauer) for radar applications are proposed. The use of this emergent technology in radar applications domains allows the development of compact and low-cost radars with multiple fields of application in daily life. In many classical UWB radar systems, only Gaussian and monocycle pulses are used. UWB waveforms based on orthogonal functions (Hermite and Gegenbauer) are proposed for there good resolution adapted more to radar detection function. There multiple access capacity due to their orthogonality presents an important advantage of these waveforms. This study proposes to compare these waveforms to Gaussian and monocycle pulses with simulations for short range avoidance collision radar application.
