Combining the detection range capability of passive radar using FM radio emissions with the range resolution obtained through the use of DVB-T signals and the elevation coverage capability provided by DAB Tx yields a high-performance hybrid passive radar sensor. Increasing the coherent integration time of the high-resolution DVB-T component in a track-before-detect approach, cued by the Doppler information obtained through the FM radio component, provides high-range resolution at extended detection ranges. In addition, the DAB-using component, cued by Doppler information provided by FM radio, extends the high-resolution detection volume to elevation ranges not illuminated by DVB-T. The heart of such a hybrid passive radar sensor will be the cued track-before-detect procedure, which is currently being developed at Fraunhofer Institute for High Frequency Physics and Radar Techniques in Wachtberg, Germany. © 2014 IEEE.

Abstract
Combining the detection range capability of passive radar using FM radio emissions with the range resolution obtained through the use of DVB-T signals and the elevation coverage capability provided by DAB Tx yields a high-performance hybrid passive radar sensor. Increasing the coherent integration time of the high-resolution DVB-T component in a track-before-detect approach, cued by the Doppler information obtained through the FM radio component, provides high-range resolution at extended detection ranges. In addition, the DAB-using component, cued by Doppler information provided by FM radio, extends the high-resolution detection volume to elevation ranges not illuminated by DVB-T. The heart of such a hybrid passive radar sensor will be the cued track-before-detect procedure, which is currently being developed at Fraunhofer Institute for High Frequency Physics and Radar Techniques in Wachtberg, Germany. © 2014 IEEE.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
