Three-dimensional human imaging for through-the-wall radar

Abstract

Three-dimensional imaging can provide more detail information of the target than two-dimensional image, which can be used to identify the target. Thus, it is very useful for detecting in enclosed structures or behind the obstacle. This paper mainly research on the three-dimensional through-the-wall human imaging and introduce an approximate method to calculate the propagation delay when electromagnetic wave passing through the wall. The refraction point can be computed directly by specific rule rather than searched the solution of complicated transcendental equation. We will design the experiment to validate the proposed method.
