Simultaneous Active and Passive SAR imaging - first results

Synthetic Aperture radar (SAR) is widely used for Earth ground imaging and mapping. In most cases, the SAR radar is an active device and can be mounted on both air- and space-borne platforms. Passive SAR imagery utilizes different illuminators of opportunity such as DVB-T, WIFI, or other active rada...

Summary:Synthetic Aperture radar (SAR) is widely used for Earth ground imaging and mapping. In most cases, the SAR radar is an active device and can be mounted on both air- and space-borne platforms. Passive SAR imagery utilizes different illuminators of opportunity such as DVB-T, WIFI, or other active radar transmitters has been gaining attention recently. In results first experimental results of passive SAR imaging have been shown in last years by researchers. Simultaneous active and passive SAR imaging is the next natural step in the development of this technology. In this paper, a system which consists of two demonstrators operates together in active (C band) and passive (DVB-T band) modes is presented. The preliminary results of the active and passive SAR imaging of the same ground area taken at the same time using a small airborne platform have been shown.
