ABSTRACT:
Methods and apparatuses for target radial extent determination using deconvolution are presented. One embodiment features a method for determining a radial extent of an target using an active sensor performing noise reduction on a received signal, deconvolving the noise reduced received signal by a transmit signal to produce a target profile, where both the noise reduced received signal and the transmit signal are over-sampled, and determining the target radial extent using the target profile. Another embodiment further features transforming the digitized transmit signal, transforming the digitized receive signal, thresholding the transformed digitized receive signal, dividing the noise reduced, transformed digitized receive signal by the transformed digitized transmit signal, and inverse transforming the divided signal.
