Space Surveillance with High-Frequency Radar [PDF]

open access: yesSensors
High-Frequency (HF) radar is well suited to the surveillance of low-earth-orbit space. For large targets, a small deployable HF radar is able to match the detection performance of much larger space surveillance radar systems operating at higher ...

Susceptibility of Commercial-Off-The-Shelf Sensors to IEMI using Pulse Modulated Signals [PDF]

open access: yesAdvances in Radio Science, 2023
The use of sensors has grown dramatically in recent years and many devices rely on the information they provide. The lack of proper security mechanisms available to control the use of sensors and the high degree of integration make them more vulnerable ...

Effects of Movement for High Time-Bandwidths in Batched Pulse Compression Range-Doppler Radar

open access: yesSensors, 2021
Radar detection and track building performance is an essential part of a radar system. A high realized coherent integration gain often contributes to an improved performance.

Comparison of DVB-T Passive Radar Simulated and Measured Bistatic RCS Values for a Pilatus PC-12 Aircraft

open access: yesSensors, 2022
Passive radar is a technology that has huge potential for airspace monitoring, taking advantage of existing transmissions. However, to predict whether particular targets can be measured in a particular scenario, it is necessary to be able to model the ...

MOBILE MAPPING BY FMCW SYNTHETIC APERTURE RADAR OPERATING AT 300 GHZ [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016
While optical cameras or laser systems are widely used for mobile mapping low attention was payed for radar systems. Due to new semiconductor technologies, compact and leight weight SAR systems based on the Frequency Modulated Continuous Wave (FMCW ...

Dealing with co‐channel interference in multi‐channel airborne passive radar

open access: yesIET Radar, Sonar & Navigation, 2021
We address the problem of co‐channel interference (CCI) in multi‐channel airborne passive radars using digital broadcast signals of opportunity. A framework for suppressing the CCI is proposed, based on a two‐stage approach, which reflects the range ...

Diffraction From Metallic Objects in Radar Imaging—Theory, Simulation, and Experimental Verification

open access: yesIEEE Journal of Microwaves, 2022
The paper describes the modelling of diffraction effects in radar imaging scans at and near sharp-edged metallic objects as the aperture dimension is close to the dimension of the object to be scanned.

Statistical Analysis of Bistatic Radar Ground Clutter for Different German Rural Environments

open access: yesSensors, 2020
This article presents the statistical analysis of bistatic radar rural ground clutter for different terrain types under low grazing angles. Compared to most state-of-the-art analysis, we present country-specific clutter analysis for subgroups of rural ...

CHALLENGES AND POTENTIALS USING MULTI ASPECT COVERAGE OF URBAN SCENES BY AIRBORNE SAR ON CIRCULAR TRAJECTORIES [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Airborne SAR on small and flexible platforms guarantees the evaluation of local damages after natural disasters and is both weather and daylight independent.
