Passive Radar System Using a Reflection of Satellite

Experimental 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...

Evaluation of active geomorphodynamics in the territory of Iran using advanced satellite radar interference techniques

Geographical extent, increasing intensity and the trend of adding new areas are the challenges of researchers and managers in the face of subsidence crisis due to the withdrawal of groundwater resources in Iran. To these challenges must be added secondary crises such as social, security, food and health consequences. In this regard, the importance of continuous and accurate monitoring in the ...

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 ...

Mapping Urban Extent Using Satellite Radar Interferometry

Phase coherence between pairs of ERS SAR images is investigated as a method for mapping urban extent in South Wales, United Kingdom. Separability indices show that image pairs with time delays of greater than 2 months and baseline separations of less than 300 m can discriminate effectively between urban and non-urban land. Classification kappa coefficients greater than 90 percent are achieved, ...
