Abstract
The method and apparatus for detecting a moving object through a barrier uses radar imaging and a multiplicity of spatially separated antennas to acquire full-waveform radar data that accurately represents the measurement of the propagating wavefield. The data is enhanced by subtracting an estimate of previously recorded background data, and beamforming of the enhanced data is performed to compute an image from the data provided on multiple channels.
