Moving Target Imaging Using GNSS-Based Passive Bistatic Synthetic Aperture Radar

open access: yesRemote Sensing, 2020
Current studies of global navigation satellite systems (GNSS)-based bistatic synthetic aperture radar (GNSS-SAR) is focused on static objects on land. However, moving target imaging is also very significant for modern SAR systems. Imaging a moving target

Translational-Invariant Ultrahigh-Resolution Spaceborne Bistatic SAR Focusing and Image Coordinate Analysis Using Bistatic Polynomial Model

open access: yesIEEE Access, 2023
We have proposed a novel process flow for translational-invariant (TI) and ultrahigh-resolution (UHR) bistatic synthetic aperture radar (BSAR) operations, wherein a UHR BSAR image is obtained via coherent integration of sub-aperture images, and its two ...

Results on bistatic synthetic aperture radar

open access: yesElectronics Letters, 2004
The interest in bistatic synthetic aperture radar (SAR) has increased rapidly in recent years. This is founded in the specific advantages of bistatic SAR configurations. The calculation of the resulting bistatic resolution is quite different from the monostatic case. A general vectorial calculation in three-dimensional space is presented.

Focusing Bistatic FMCW SAR Signal by Range Migration Algorithm Based on Fresnel Approximation

open access: yesSensors, 2015
Frequency modulated continuous wave (FMCW) technique has recently been employed by synthetic aperture radar (SAR) to decrease the radar cost and volume. However, the operation range is limited by the direct energy leakage from the transmitting channel to

A Fast Bistatic ISAR Imaging Approach for Rapidly Spinning Targets via Exploiting SAR Technique

open access: yesRemote Sensing, 2020
Because of the large range of cell migration (RCM) and nonstationary Doppler frequency modulation (DFM) produced by non-cooperative targets with rapid spinning motions, it is difficult to efficiently generate a well-focused bistatic inverse synthetic ...
