detection of moving targets in stepped-frequency radars using dcft
one of the most common signals used for achieving high range resolution in radar is stepped-frequency signals. when a target is stationary in these radars, dft (discrete fourier transform) based processing is used to attain high range resolution profile (hrrp). however, in the case of moving target, due to spreading of the echo signal spectrum, dft based processing is not optimal and decreases ...
متن کاملDetection/Tracking of moving targets with synthetic aperture radars
In this work, the problem of detecting and tracking targets with synthetic aperture radars is considered. A novel approach in which prior knowledge on target motion is assumed to be known for small patches within the field of view. Probability densities are derived as priors on the moving target signature within backprojected SAR images, based on the work of Jao. Furthermore, detection and trac...
متن کاملmoving target detection in stepped frequency radars using compressive sensing
stepped frequency radars attract many attentions due to their high range resolution. conventional processing technique in these radars is based on the idft. in detecting moving targets, the idft has the problems of range shifting and range spreading, which result in degrading target amplitude, loss of range accuracy and range resolution. to overcome these problems, the velocity compensation met...

In through-the-wall radar and urban sensing applications, detection, localization, and classification of targets are highly desirable. The presence of the targets inside buildings, and in close proximity of walls, floors, and ceilings, leads to a rich multipath environment. Multipaths can introduce false targets, thereby degrading target detection, localization, and classification performances....
