The Radiometric Measurement Quantity for SAR Images

, 2013
A Synthetic Aperture Radar (SAR) system measures among other quantities the terrain radar reflectivity. After image calibration, the pixel intensities are commonly expressed in terms of radar cross sections (for point targets) or as backscatter ...

Resident space object passive bistatic radar detection using DVB-S2 signals

, 2018
Monitoring objects in Earth's orbit and preventing collisions is becoming an increasingly widespread task. In this regard, several monitoring systems using different type of sensors have been developed over time: Optical, Laser and Radar.

Mitigating the effect of direct signal interference in passive bistatic radar

, 2009
Passive bistatic radar uses target illuminations by transmitters of opportunity (often commercial broadcasts). Unfortunately, the strength of the direct signal interference (DSI) can often be so strong as to mask target returns.

A Coherent Integration Method for Moving Target Detection in Frequency Agile Signal-Based Passive Bistatic Radar

Remote Sensing
In this paper, the possibility of improving target detection performance in passive bistatic radar by exploiting a frequency agile (FA) signal is investigated, namely frequency agile signal-based passive bistatic radar (FAPBR) coherent integration. Since

Modelling and simulation of passive bistatic radar

, 2017
Passive bistatic radar (PBR) systems have separate transmitter and receiver. It usually uses a third-party transmitter to track targets. Transmitter and receiver are widely spaced. Passive radar has a lot of advantages compared to monostatic radar. It is
