CHARACTERISATION OF THE ITERATIVE MULTI-PARAMETER (IMP) ALGORITHM
JL MATHER · 2024
The incremental multi parameter (IMP) algorithm will be described.This algorithm is used to analyse data from arrays of sensors in order to estimate signal parameters.It makes use of the conventional beamformer as a key component of an iterative analysis of the data, yet is able to outperform alternative "high resolution" estimators such as MUSIC by 10-15dB.The algorithm is suitable for use with general array geometries, and is also capable of handling single snapshot data and coherent signals.This paper outlines the algorithm and compares the performance of IMP, MUSIC and RootMUSlC, as assessed by Monte Carlo trials.
