Smith, and postdoctoral researcher Okan Yurduseven describe a method for through-wall imaging (TWI) that compensates for the varied distortion produced by different wall materials, to allow details to be captured more accurately.<\/p>\n<p>&#8220;[I]n many practical situations, both the object to be imaged and the structure of the intervening medium are unknown,&#8221; the paper explains. &#8220;Unfortunately, the medium then adds confounding variables so that the scattered field sampled by the sensor may no longer be sufficient to determine both the medium and object structures.&#8221;<\/p>\n<p>The paper describes a variety of ways to capture images through walls using microwave radiation. These techniques have already made their way into commercial products like L-3 CyTerra&#8217;s RANGE-R and Camero-Tech&#8217;s XAVER line of handheld through-wall radar units. The devices start at about $6,000.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"<p>The Register (UK): Looking through walls, now easier than ever by Thomas Claburn: Boffins working to put everyone in glass houses [Kyllo redux, with better technology]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[76],"tags":[],"class_list":["post-30553","post","type-post","status-publish","format-standard","hentry","category-surveillance-technology"],"_links":{"self":[{"href":"https:\/\/fourthamendment.com\/index.php?rest_route=\/wp\/v2\/posts\/30553","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/fourthamendment.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/fourthamendment.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/fourthamendment.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/fourthamendment.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=30553"}],"version-history":[{"count":7,"href":"https:\/\/fourthamendment.com\/index.php?rest_route=\/wp\/v2\/posts\/30553\/revisions"}],"predecessor-version":[{"id":30561,"href":"https:\/\/fourthamendment.com\/index.php?rest_route=\/wp\/v2\/posts\/30553\/revisions\/30561"}],"wp:attachment":[{"href":"https:\/\/fourthamendment.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=30553"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/fourthamendment.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=30553"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/fourthamendment.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=30553"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
