Passive Radar Imaging and Target Recognition using Illuminators of Opportunity
نویسنده
چکیده
1) Target recognition via radar cross section (RCS) profiles: In this approach, databases of the RCS of targets at different incident and observed angles are created using method-of-moments computational electromagnetics codes. The extracted RCS profiles for different targets, scaled to account for antenna patterns and atmospheric propagation, are compared to the collected data. A coordinated flight model is used to estimate the aircraft's orientation along its flight path. The low frequencies used in passive radar naturally give stable features well suited for automatic target recognition.

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 ...
متن کاملAutomated Target Recognition Using Passive Radar and Coordinated Flight Models
Rather than emitting pulses, passive radar systems rely on illuminators of opportunity, such as TV and FM radio, to illuminate potential targets. These systems are particularly attractive since they allow receivers to operate without emitting energy, rendering them covert. Many existing passive radar systems estimate the locations and velocities of targets. This paper focuses on adding an autom...
متن کاملExperimental Results Using Satellite Illuminator for Passive Bistatic Radar
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...

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 association ambiguity between the measurements and targets, which introduces a significantly complex t...
متن کاملFeasibility Study of EO SARs as Opportunity Illuminators in Passive Radars: PAZ-Based Case Study
Passive radars exploit the signal transmitted by other systems, known as opportunity illuminators (OIs), instead of using their own transmitter. Due to its almost total invulnerability to natural disasters or physical attacks, satellite OIs are of special interest. In this line, a feasibility study of Earth Observation Synthetic Aperture Radar (EO SAR) systems as OIs is carried out taking into ...
