<p>The method involves the time-separated transmission of N (greater than 2) periodic electromagnetic signals with half wavelengths Lamda 1>. Received signals are sampled with equi-temporal sampling timing. Signals from K targets comprise reflected and superposed signal components, and M samples are taken per signal period. Distances to the K targets are determined simultaneously from the sampled values using the phase measurement principle. A statistical parameter estimation problem based on a mathematical signal model is solved by defining the number of targets for more than one target, or determining the number of targets based on a method involving satisfying inequalities. An independent claim is included for a computer program product.</p> |
