Passive bistatic radar enhancement devices

Proceedings of the IEE Part C: Monographs, 1962
The 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

2012
In 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, 2018
The 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, 2003
In 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

VHF airborne passive bistatic radar ground clutter investigation

IET International Conference on Radar Systems (Radar 2012), 2012
Airborne 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, 2016
Passive 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, 2011
Digital 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

2018
This 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.

Bistatic passive radar simulator with spatial filtering subsystem

SPIE Proceedings, 2009
The purpose of this paper is to briefly introduce the structure and features of the developed virtual passive FM radar implemented in Matlab system of numerical computations and to present many alternative ways of its performance. An idea of the proposed solution is based on analytic representation of transmitted direct signals and reflected echo ...

Multiple Target Parameter Estimation in Bistatic Passive Radar

2019 IEEE Radar Conference (RadarConf), 2019
An expectation-maximization (EM)-based iterative algorithm is proposed for jointly estimating the delay and Doppler parameters of multiple moving targets in a bistatic passive radar system. In the E-step, the expectation of the log-likelihood function, with respect to the unobserved illuminator waveform and conditioned on the observed signals in the ...
