Adaptive Radio Frequency Interference Mitigation for Passive Bistatic Radar Using OFDM Waveform

Passive Bistatic Radar and Waveform Diversity

This tutorial describes the basis of passive bistatic radar (PBR) systems, and in particular the nature of the waveforms of illuminators of opportunity that they exploit. It shows that there is a wide variety of such waveforms, from broadcast, communications and radionavigation transmissions, and that in general they are not optimum for radar purposes. In addition, they usually vary significant...

Radio Frequency Interference Mitigation in Radio Astronomy

Bistatic Passive Radar Demonstrator Using COTS

A low-cost passive bistatic radar system using digital video broadcasting satellites (DVB-S) as illuminators of opportunity is presented. The system was developed using off-the-shelf components which a global cost of approximately 100 Euros. To increase the target detectability using DVB-S signals in a non-coherent environment a novel methodology, using a reference target and some basic signal ...

Exascale Real-Time Radio Frequency Interference Mitigation

Radio Frequency Interference (RFI) mitigation is extremely important to take advantage of the vastly improved bandwidth, sensitivity, and field-of-view of exascale telescopes. For current instruments, RFI mitigation is typically done offline, and in some cases (partially) manually. At the same time, it is clear that due to the high bandwidth requirements, RFI mitigation will have to be done aut...

FM radio based bistatic radar

An experimental bistatic radar system is described that detects and tracks targets to ranges in excess of 150 km from the receiver, using echoes from a non-cooperative FM radio transmitter. The system concept and limitations on performance are described, followed by details of the processing used to implement the system. An adaptive filter algorithm is described that is used to efficiently remo...
