Localization Capability of Cooperative Anti-Intruder Radar Systems
EURASIP Journal on Advances in Signal Processing, 2008 System aspects of an anti-intruder multistatic radar based on impulse radio ultrawideband (UWB) technology are addressed. The investigated system is composed of one transmitting node and at least three receiving nodes, positioned in the surveillance area

Digital Beamforming on Receive: Techniques and Optimization Strategies for High-Resolution Wide-Swath SAR Imaging [PDF]
, 2009 Synthetic Aperture Radar (SAR) is a well-proven imaging technique for remote sensing of the earth. However, conventional SAR systems are not capable to fulfill the increasing demands for im-proved spatial resolution and wider swath coverage.

Relativistic Effects in Bistatic SAR Processing and System Synchronization [PDF]
, 2012 This paper addresses relativistic effects in bistatic and multistatic SAR systems and missions. It is shown that the use of different reference frames for bistatic SAR processing and bistatic radar synchronization is prone to nota-ble phase and time ...

Multistatic Radar: System Requirements and Experimental Validation
, 2014 Multistatic radar provides many advantages over conventional monostatic radar, such as enhanced information on target signatures and improvements in detection which are due to the multiple perspectives and differences in the properties of clutter ...

Digital Beamforming and Non-Uniform Displaced Phase Centre Sampling in Bi- and Multistatic SAR [PDF]
, 2004 The displaced phase centre (DPC) technique will enable a wide swath SAR with high azimuth resolution. In a classic DPC system, the PRF has to be chosen such that the SAR carrier moves just one half of its antenna length between subsequent radar pulses ...

International Journal of Antennas and Propagation, 2019 In this paper, an estimation algorithm for the position and velocity of a moving target in a multistatic radar system is investigated. Estimation accuracy is improved by using bistatic range (BR), time-difference-of-arrival (TDOA), and Doppler shifts ...
