This letter considers the problem of building layout determination using through-wall-radar imaging technology, which employs multiple transmit–receive channels to implement multiview synthetic aperture imaging. In each view, the phase errors of multichannel data introduced by the unknown walls deteriorate significantly the performance of the coherently data-combined algorithm by Le <etal/>...
In the building environment of through-wall-radar imaging, multi-path clutter generates ghost images and defocuses target images, and the ambiguities of wall parameters lead to the defocusing of target images. These two problems reduce the signal-to-clutter ratio of image, which makes it difficult to robustly implement target detection in image domain. In this paper, multi-channel through-wall-radar...
This paper mainly deals with target detection under heavy clutters in through-the-wall-radar imaging, and based on random sparse array, proposes an approach of multi-channel target cooperative detection with modified N-K detector applied to multiple single-channel images.
