In recent years passive radar systems research has been increasingly focused on the use of satellite opportunity signals, and DVB-S signals in particular, since these offer virtually global coverage. Several papers have been published recently proving the effectiveness of very simple demonstrators based...
This paper gives the performance research on the ambiguity function and resolution of passive radar based on DVB-S (Digital Video Broadcasting-Satellite) signal. The radar system structure and signal model of DVB-S signal are firstly studied, then the am

Passive radar,Satellites,Surveillance,Object detection,Radar antennas,Propagation losses,FacesPassive Radars (PRs) are promising emerging technologies to face new security requirements. Satellite illuminators are of great interest due to their nearby global coverage and availability, operating frequencies and ...
This paper investigates the possibility to improve target detection capability in a DVB-T- based passive radar sensor by jointly exploiting multiple digital television channels broadcast by the same transmitter of opportunity. Based on the remark...
Passive radar detects moving targets by Cross Ambiguity Function (CAF), which is based on the cross correlation process of the direct-path signal in reference channel and echo signal in receive channel. Thus, the performance of direct-path signal is important to system performance for this type ...
The target tracking using multistatic passive radar in a digital audio/video broadcast (DAB/DVB) network with illuminators of opportunity faces two main challenges: the first challenge is that one has to solve the measurement-to-illuminator association ambiguity in addition to the conventional ...

Main advantages of employing DVB-S as Illumina-tor of Opportunity for passive radar is high availability, but the power scattered from targets is really low. In this paper, the design of a surveillance antenna capable of fulfilling the requirements defined by the DVB-S passive radar, is ...
