A study of bistatic radar and the development of an independent bistatic radar receiver
This report contains a literature review of bistatic radar and also describes an experimental L-Band bistatic radar receiver which was built at the University of Cape Town. In a bistatic radar the transmitter and receiver are separated by an amount which is comparable to the distance to the targets …

Design of an HF transmit antenna for bistatic ionospheric soundings in Antarctica
… (HF) transmitter at the South Pole for use in a bistatic ionospheric sounding system intended to detect such TIDs. The aim of this dissertation was to design a suitable transmitter antenna such that propagating skywave signals could successfully be received by the SANAE SuperDARN radar some 2090 …

Using GPS bistatic signal for land and ocean remote sensing in South Africa
This project discusses the basic principles and theory of this new technology, and concentrates on reflection points and Fresnel zones. The CPS receivers are placed at different coastal regions within South Africa, and the simulation of the reflection points and Fresnel zones are observed as the …

Synthetic Aperture Radar Image Formation for the Moving -Target and Near -Field Bistatic Cases
Bistatic SAR imaging is more involved than the monostatic SAR case, because of the separation of the transmitter and the receiver, and possibly the changing bistatic geometry. For near-field bistatic SAR imaging, we develop a novel fast BP algorithm, motivated by a newly proposed fast BP algorithm …

Using a bistatic Fabry-Perot interferometer system to improve the estimation of thermospheric winds
… complex struc- tures in the wind eld. However, a bistatic FPI system (BFPIS) can be used to obtain full vector wind information in two or more locations. This observa- tion methodology also has potential for reducing the number of assumptions that must be made. For a BFPIS, it need only be assumed …

Integrated perception, modeling, and control paradigm for bistatic sonar tracking by autonomous underwater vehicles
In this thesis, a fully autonomous and persistent bistatic anti-submarine warfare (ASW) surveillance solution is developed using the autonomous underwater vehicles (AUVs). The passive receivers are carried by these AUVs, and are physically separated from the cooperative active sources. These …

Mission Planning Tool for space debris studies with the MeerKAT radar
… Africa. The MeerKAT radar is intended to operate bistatically, with a transmitter located in Bredasdorp (South Africa) and the MeerKAT radio telescope as receiver. The system design and radar signal processing design are currently under development in another RRSG project. Before the feasibility …
