Application of Communication Signals for Remote Sensing

The paper presents the concept of applying different communication signals as illuminating signals in a remote sensing application. Classical remote sensing in radio frequency and microwave regions is based on active radar technology. When specially designed, in most cases a pulse signal is sent by the radar to illuminate the sensing scene and the return echo is analyzed. As more and more communication signals are freely available in the surveillance space, microwave sensing without its own illumination has been the focus of increasing interest. In the paper detailed discussion of the properties of different signals for remote sensing is presented, together with experimental results carried out at the Warsaw University of Technology, Poland.
