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 and Development of an RF-SoC-Based Ultra-Wideband Radar for Remote Sensing of Snow
… explores the potential of ultra-wideband (UWB) radar integrated with small Unmanned Aircraft Systems (sUAS) to bridge these gaps. The goal is to develop a UWB radar system capable of generating a snow water equivalent (SWE) product from sUAS. The radar operates in both monostatic and bistatic …

Performance prediction and improvement of a Bistatic Passive coherent location Radar.
Passive Coherent Location (PCL) radar has proved to be feasible in a number of experimental systems, but the lack of comprehensive, published flight trials detracts somewhat from serious consideration of these PCL systems for operational applications, such as Air Traffic Control (ATC). The carrying …

Effects of the troposphere upon radio communications and implications for weather measurement
… the required measurements by means of a passive bistatic radar setup with a cooperative target. Such an approach overcomes the timing problems that are normally associated with propagation measurements. A network of these measurements can then be assimilated into a numerical weather prediction …

Electronic countermeasures applied to passive radar
Passive Radar (PR) is a form of bistatic radar that utilises existing transmitter infrastructure such as FM radio, digital audio and video broadcasts (DAB and DVB-T/T2), cellular base station transmitters, and satellite-borne illuminators like DVB-S instead of a dedicated radar transmitter. …

Observation of Low Earth Orbit Debris using GNSS Radar
… transmitter segment of bi-static or multi-static radars. In this work, we focus on GNSS as an emitter of opportunity to enhance Space Situational Awareness (SSA) by tracking small items of space debris using bistatic radar. However, the scattered GNSS signal levels from small items of space debris …
