Abstract
A mathematic model of through-wall electromagnetic wave is constructed. The path of microwave penetrating wall is resolved. The extra time delay is compensated according to microwave passing through wall. The back projection method of through-wall stepped frequency signals is deduced. The arithmetic realization flow is also given. The imaging result is simulated according to the arithmetic flow, including both defocused and focused circumstance, and the influence of the thickness and dielectric constant of the wall is analyzed. The simulation result proves the efficiency of the arithmetic.
