End-to-End Monocular Range Estimation for Forward Collision Warning [PDF]
Sensors, 2020 Estimating range to the closest object in front is the core component of the forward collision warning (FCW) system. Previous monocular range estimation methods mostly involve two sequential steps of object detection and range estimation.

Quantum-Limited Estimation of Range and Velocity [PDF]
PRX Quantum, 2021 The energy-time uncertainty relation puts a fundamental limit on the precision of lidars for the estimation of range and velocity. The precision in the estimation of the range (through the time of arrival) and the velocity (through Doppler frequency ...

Dynamic-range estimation [PDF]
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2006 It has been widely recognized that the dynamic-range information of an application can be exploited to reduce the datapath bitwidth of either processors or application-specific integrated circuits and, therefore, the overall circuit area, delay, and power consumption.

Joint Range Estimation Using Single Carrier Burst Signals for Networked UAVs
IEEE Access, 2021 The localization accuracy demand is ever growing in UAV communication networks. We propose a joint coarse and fine range estimation method using single carrier burst signals with two samples per symbol for UAV networks. The coarse estimation of our joint

Positron range estimations with PeneloPET [PDF]
Physics in Medicine and Biology, 2013 Technical advances towards high resolution PET imaging try to overcome the inherent physical limitations to spatial resolution. Positrons travel in tissue until they annihilate into the two gamma photons detected. This range is the main detector-independent contribution to PET imaging blurring.
