Abstract: An apparatus configured to:



receive an input dataset indicative of the amplitude and phase of radar signals received at a plurality of antenna elements;
determine an objective function;
determine a beam forming spectrum, the beam forming spectrum comprising a correlation of the input dataset with a set of beamsteering vectors;
perform a first determination process for evaluation of the objective function comprising the processor being configured to:

identify two or more peaks in the beam forming spectrum based on a predetermined threshold level, determine candidate direction-of-arrival angles therefrom for definition of a first-reduced search space;


perform a second determination process for evaluation of the objective function comprising the processor being configured to:

determine a peak direction-of-arrival angle comprising the direction-of-arrival angle that corresponds to a peak in the beam forming spectrum:


evaluate the objective function over the first reduced search space and using the peak direction-of-arrival angle.
