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 ...

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

Measurements of the Multistatic X&L Band Radar Signatures of UAVS [PDF]

, 2020
This paper illustrates the results of a series of measurements of multistatic radar signatures of small UAVs at L and X band. The system employed was the multistatic multiband radar system, NeXtRAD, consisting of one monostatic transmitter-receiver and ...

DETECTION OF MULTIPLE TARGETS BY A MULTISTATIC RADAR

Perner’s Contacts, 2009
Multistatic radar systems with several transmitters and receivers introduce not only new qualities in area surveillance as well as in hardware minimization but also new problems in signal processing and target detection and tracking.

Joint Position and Velocity Estimation of a Moving Target in Multistatic Radar by Bistatic Range, TDOA, and Doppler Shifts

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 ...

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.
