Investigation of ducts as a “radar pinhole” for detecting objects through a wall [PDF]
, 2016 There is a continuing interest in the through-the-wall capabilities of radar. It has been found that walls behave as a low-pass medium, and therefore through-the-wall radar has been restricted to frequencies in the low GHz range.
