Misspecified Time-Delay and Doppler Estimation over Non Gaussian Scenarios

ICASSP 2024accepted

Time-delay and Doppler estimation is an operation performed in a plethora of engineering applications. A common hypothesis underlying most of the existing works is that the noise of the true and assumed signal model follows a centered complex normal distribution. However, everyday practice shows tha…

On The Accuracy Limit of Joint Time-Delay/Doppler/Acceleration Estimation with a Band-Limited Signal

Hamish McPhee, Lorenzo Ortega, Jordi Vilà-Valls, Eric Chaumette

ICASSP 2021accepted

The derivation of estimation lower bounds is paramount to design and assess the performance of new estimators. A lot of effort has been devoted to the joint distance-velocity estimation problem, but very few works deal with acceleration, being a key aspect in several high-dynamics applications. Cons…
