The authors analysed a set of random frequency modulated (FM) signals for wideband radar
imaging and assessed their resolution capability and sidelobe distribution on the range …

Histogram specification has been successfully used in digital image processing over the
years. Mainly used as an image enhancement technique, methods such as histogram …

Imaging a fast maneuvering target has been an active research area in past decades.
Usually, an array antenna with multiple elements is implemented to avoid the motion …

We address the problem of airborne high resolution two-dimensional inverse synthetic
aperture radar (ISAR) side-view imaging of ship targets. Using a simple model of the ship …

An adaptive joint time–frequency algorithm has been applied and evaluated for focusing
distorted ISAR (inverse synthetic aperture radar) images when the target motion is confined …

During lung sound recordings, heart sounds (HS) interfere with clinical interpretation of lung
sounds over the low frequency components which is significant especially at low flow rates …

Subarray averaging and entropy minimization (SAEM) algorithm is applied to stepped-
frequency ISAR autofocus to compensate for the phase error along the down-range due to …

This paper presents a system model and method for the 2-D imaging application via a
narrowband multiple-input multiple-output (MIMO) radar system with two perpendicular …

This paper describes, for the first time to the authors' knowledge, the phenomenon of
nonuniform azimuth image shift of a rigid body observed in the Radarsat synthetic aperture …

The surroundings of underground mining machines still constitute an unsafe area for miners
due to bad visibility conditions. In this paper, we present a novel acoustic position estimation …
