Surrounding Vehicle Distance Estimation using Impulse Radio Ultra-Wideband

In this paper, we propose an impulse radio ultra wideband based algorithm for distance estimation between vehicles and computer simulations are used to verify distance performance and accuracy. The distance estimation between vehicles configures the transceiver between the ego vehicle and the target vehicle and estimates the distance between vehicles by calculating the delay distance of the original signal through a cross-correlator of the waveform. The estimated distance between vehicles through experiments can provide high accuracy within 1 m on average. Simple algorithms can also be applied to avoid collisions between vehicles or to measure distances between vehicles and infrastructure by providing fast throughput.
