The use of passive or parasitic radars has been an active area of research recently. Such radars mostly depend on communication emitters of opportunity. One recent development in the field of communication engineering is the newly adopted standards for whitespace communication which frees the usage of analog TV bands. These bands because of their low-frequency nature, are suitable for foliage penetration (FOPEN). This paper investigates the use of whitespace communication for commensal use as a FOPEN radar system. It proposes the architecture of such an integrated communication radar (COMMRAD) system and concludes that such an FOPEN system is possible using the whitespace bands.
