Multi Band FM and DVB-T2 Passive Radar Demonstrator

Waveform Selection For Multi-Band Multistatic Radar Networks

“…In order to make this decision, the knowledge of active radar performance versus passive radar performance is required. blueTherefore, the purpose of this study is to investigate the theoretical performance limits of multi-waveform hybrid multistatic radar networks since multi-waveform receivers, which can exploit broadcasting signals and radar waveforms for sensing, have been recently developed and implemented such as in [6,7,8]. However, the theoretical performance limits of multi-waveform multistatic radar networks consisting of such receivers have not been systematically investigated.…”

“…FM radio signals have been considered for passive radars especially because of their high transmit power, low path-loss transmission due to their low carrier frequency and widely availability around the world. Although the range resolution of FM signals are limited due to their narrow band and highly content-dependent spectrum, they can be effectively utilised for estimating target velocity [7]. Multi-band passive radar receivers utilising broadcasting signals were successfully developed, implemented and tested in real-time measurements [8,7].…”

Multi-band passive radar receivers utilising broadcasting signals were successfully developed, implemented and tested in real-time measurements [8,7]. For examples, a multi-band passive radar system utilising FM and DVB-T signals were developed and tested in a real scenario [7], where 4 seconds coherent processing interval (CPI) was chosen for FM radio signals with average 80 kHz bandwidth while the DVB-T based PBR system exploited one DVB-T frame with 7.7 MHz bandwidth for sensing.…”

The range resolution of the FM based PBR was relatively large, between 2 and 3 km throughout the measurements, but it delivered a fine Doppler resolution of 0.25 Hz.…”

“…Multi-band receivers equipped with multiple surveillance and reference antennas are placed at different locations so that the range and velocity estimations are overall improved in the multistatic radar network. Such multi-band multi-illuminator passive radar receivers have already been developed, implemented and measured to evaluate their performance [8,7] which demonstrate that FM, DAB, DVB-T can be jointly and efficiently utilised for passive bistatic sensing. There are significant advantages of utilising multiple sources operating at different frequency bands.…”
