Abstract :
An effective procedure for estimation of line parameters using time-frequency (TF) representations and the subspace-based line detection (SLIDE) algorithm is presented. The line parameters are mapped into the instantaneous frequency (IF) of frequency modulated (FM) signals. The IF is estimated by using the TF representation. A new propagation approach is proposed. Performance of the proposed approach and the variable μ-propagation method are compared.
