Abstract

Radar apparatus for detecting an object in through wall and related applications, the radar apparatus comprising a transmitter for transmitting radar signals, and a receiver for receiving reflected portions of said transmitted signals from said object. The radar apparatus is configured for operation in any of at least a first and a second selectable mode. The transmitter is configured for transmitting radar signals in accordance with a selected one of the modes of operation, and said receiver is configured for receiving said reflected portions of said signals transmitted in accordance with said selected mode of operation. The radar apparatus is configured for transmission of signals, through an obstacle, to said object when operating in at least one of said modes.
