Method for processing multipath and related device

摘要

The multiple path processing method analyses two successive digital interrogation transmissions. Only those paths without ambiguity are retained, other paths are rejected (23,32). The first returned path is considered the most likely response. Energy levels are measured and energy dispersion calculated (2) normalising the variance of elements of each channel and comparing (10) valid dispersions on n-channels similar dispersion outputs to form a multipath reduced output (12).
