Detecting a target of interest such as a breast tumour is the primary focus of microwave imaging but once detected an additional useful property to have is some measure of the target shape. A combination of a pseudo-random noise (PN) sequence and filter has been employed to pick out the edges of a target that when used to create an image shows the target's shape clearly. A variety of target shapes are investigated with each image giving a good detection and showing the target's shape. Imaging through an outer shell to an inner target and showing both the shell and target on the image is successful with the PN sequence and filter but fails when using a wideband pulse and integrating along its length, picking up only the inner target.
