recently many studies have been done on different issues of using multiple antennas at transmit and receive sides of a radar system in a mimo (multiple input multiple output) configuration. in addition, for the electronic warfare‟s purposes, the utilization of available signals of the environment to detect the targets has gained considerable attention in recent years. such passive radars use th...

This report investigates the suitability of a number of broadcast band transmitters of opportunity for a passive radar. Specifically, this report reviews the design of active radar waveforms, measures emissions for representative transmitters of opportunity, and assesses the suitability of these signals for various types of radar observation. This report shows that it is indeed possible to cons...

This paper examines the feasibility of Long Term Evolution (LTE)-based passive radar for detecting ground moving targets. Specifically, the focus of this paper is to describe the proposed LTE-based passive radar system and to conduct an experiment using a real LTE eNB transmitter as an illumination source. Seven scenarios were carried out to investigate the detection performance of the proposed...

The passive radar is a hot research topic. A multi-channel wideband passive radar experimental system is designed and the digital television terrestrial broadcasting (DTTB) signal is chosen to carry out the target detection experiment of civil aviation aircraft. The polarization and spatial filtering methods are used to solve the strong direct path interference suppression problems brought by t...

We investigate passive radar imaging of aircraft using re ected TV signals. Such passive multistatic \radar" has been developed to detect and track aircraft with good accuracy. The additional capability of image formation would help to identify targets. The Fourier space sampling provided by passive radar is nonuniform. For a given aircraft ight path, di erent receiver locations give rise to di...

Passive, bistatic radar offers an attractive method for remotely detecting and imaging targets without the requirement of a dedicated transmitter. Passive radar systems are usually cheaper than their active counterparts, which easily allows for multi-sensor networks. Furthermore, passive radar systems are difficult to detect and jam. With these advantages come several challenges, however. Bista...

We adapt and apply a recently-developed region-enhanced synthetic aperture radar (SAR) image reconstruction technique to the problem of passive radar imaging. One goal in passive radar imaging is to form images of aircraft using signals transmitted by commercial radio and television stations that are reflected from the objects of interest. This involves reconstructing an image from sparse sampl...

this paper addresses the signal processing principles in passive bistatic radar (pbr) systems. in this case, the detection problem in the presence of system noise, clutter/multipath, direct signal and interfering target signals is investigated. to this light, two types of detectors are studied. in the first one, which is based on intuitive sense, we examine two detectors. in the second type det...
