Estimation of passive bistatic radar detection probability: Experimental results
2014 11th European Radar Conference, 2014This work is focussed on the estimation of the detection probability for Passive Bistatic Radar (PBR) systems. The aim of this work is to develop a methodology for estimating the probability of detection from real data. Two techniques have been introduced and compared in terms of Receiver Operating Curves (ROC) in a real scenario with a cooperative ...

Passive bistatic radar enhancement devices
Proceedings of the IEE Part C: Monographs, 1962The usual enhancement devices are constructed to give a maximum monostatic echo area. This is achieved by setting up a uniform phase distribution in the effective aperture of the device independent of the angle of incidence. Bistatic echo-area enhancement may be achieved by altering this phase distribution.

Advanced Processing Methods for Passive Bistatic Radar Systems
2012In this chapter, after introducing the main scheme for a passive bistatic radar signal processor, advanced processing techniques have been illustrated to perform optimized detection with such sensors. In particular, the most essential steps of 2D-CCF evaluation and interference cancellation have been described in detail, showing their optimization in ...

Detection of supersonic rockets using passive bistatic radar
IEEE Aerospace and Electronic Systems Magazine, 2018The history of rockets starts in antiquity, and has continued through to modern times. The modern rocket era started before World War II (WWII), when amateur rocket engineers were building and launching their rockets. During WWII rocket technology was closely associated with weapon development, with the famous V2 rocket as the most notable example ...

Passive bistatic radar sensing with LEOS based transmitters
IEEE International Geoscience and Remote Sensing Symposium, 2003In this paper we describe the concept of a bistatic SAR system which involves a purpose built stationary ground based receiver but which utilizes existing or proposed low earth orbit satellite (LEOS) communication systems, such as Globalstar or ICO as the transmitting signal sources. In general, such a system has a 3-D configuration (in contrast to the

GLRT-Based CFAR Detection in Passive Bistatic Radar
IEEE Transactions on Aerospace and Electronic Systems, 2013The work presented here addresses the problem of detecting a target in a passive bistatic radar (PBR) in the presence of interference signals, including receiver noise, direct signal, multipath/clutter echoes, and interfering targets. To this end, after outlining the model of the detection problem in the surveillance channel as a composite hypothesis ...

VHF airborne passive bistatic radar ground clutter investigation
IET International Conference on Radar Systems (Radar 2012), 2012Airborne passive bistatic radar is currently experiencing renewed interest for both air-to-air and air-to-ground operation. An experimental airborne passive bistatic radar demonstrator system, that uses FM broadcast transmissions as an illuminator of opportunity, has been designed and constructed and flown on airborne experiments to collect data.

Compressive sensing based high-resolution passive bistatic radar
SIGNAL, IMAGE AND VIDEO PROCESSING, 2016Passive bistatic radar (PBR) systems using different communication signals can only offer low-resolution target detection due to their inherent low bandwidth. In this paper, compressive sensing (CS) is applied to multichannel FM and GSM PBR to achieve improved range-Doppler resolutions and avoid some limitations of classical multiband PBR processing ...

HF passive bistatic radar based on DRM illuminators
Proceedings of 2011 IEEE CIE International Conference on Radar, 2011Digital Radio Mondiale (DRM)-based HF passive bistatic radar has massive potential for surveillance purposes. Progress about DRM based passive bistatic radar is described. Several key problems need to be overcome for the base-band signal processing, including the vice-peaks suppression of DRM signal ambiguity function, the rejection of direct-path and ...

Passive bistatic radar for spectrum sharing
2018This chapter has provided a brief introduction to the properties of PBR, and considered how PBR may be able to help address spectral congestion. The problem itself is already severe, and is likely to get worse. But there are some grounds for optimism, and PBR certainly has a part to play in providing solutions.
