Future developments promise to image through multiple walls and even penetrate whole buildings using distributed sensors on or around buildings, carried by Soldiers, vehicles, even UAVs.
Imagine a commander being able to drive or fly down a city block and monitor buildings on both sides of the street, to find occupants inside, determine the layouts of the buildings, and locate weapon caches.

January 15, 2006 There was once a time when a concrete wall on the battlefield meant that a soldier was both safe from bullets and invisible to the enemy. Thanks to the coming XM25 Advanced Airburst Weapon System and DARPA’s latest invention, the “Radar Scope”, the concrete wall has now been rendered useless on both counts. The new "Radar Scope" offers warfighters the very same x-ray vision with which SuperMan captivated a generation of youngsters – it can see through walls. The Radar Scope is a light-weight, low-cost, through-wall personnel detector that uses stepped-frequency radar to detect subtle changes in Doppler signature of the returned signal. Put simply, it is a motion detector that can see through walls.
