Investigations on the Advanced SAR Processing Algorithms for Security Applications With Distributed Sensing

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
A distributed airborne/spaceborne synthetic aperture radar (SAR) system that consists of a set of monostatic and/or bistatic SARs offers many advantages thanks to the bi-/multiaperture reception.

Assessment of Hongtu-1 Multi-Static X-Band SAR Constellation Interferometry

Remote Sensing
In 2023, the Chinese company PIESAT launched the multi-static X-band SAR constellation Hongtu-1 (HT1). HT1 consists of the active monostatic SAR sensor HT1-A and the three additional passive SAR receivers HT1-B, HT1-C and HT1-D.

Through-wall multistatic polarimetric 3D SAR

, 2022
Through-Wall (TW) Synthetic Aperture Radar (SAR) imagery can be difficult to interpret due to several factors including signal attenuation in highly cluttered environments, target overlay, difficult to interpret low SAR resolution and low frequency scattering responses.

Multistatic and multi-aspect SAR data acquisition to improve image interpretation

, 2022
S.4194-4197Synthetic Aperture Radar (SAR) images sometimes suffer from shadowing effects, and therefore objects of interest are often not visible. Further, the reflectivity of objects strongly depends on the acquisition geometry.

Layer-optimized synthetic aperture radar processing with a mobile phase-sensitive radar: a proof of concept for detecting the deep englacial stratigraphy of Colle Gnifetti, Switzerland and Italy [PDF]

The Cryosphere
Radio-echo sounding is a standard technique for imaging the englacial stratigraphy of glaciers and ice sheets. In most cases, internal reflection horizons (IRHs) represent former glacier surfaces, comprise information about past accumulation and ice ...

Highly Integrated Low-Profile Multilayer Dual-Polarized Phased Array Antenna With Truncated Cavities for First Pulsed Bistatic L-Band Airborne SAR Sensor

IEEE Access
Synthetic Aperture Radar (SAR) has become, nowadays, one of the most important techniques in remote-sensing, and the increasing interest in Earth monitoring reinforces this trend. Next-generation SAR sensors will enhance the radar resolution capabilities

Study on Simulation Technology of Bi-/multistatic SAR Radio Echo

, 2019
: A real-time bi-/multistatic synthetic aperture radar (SAR) radio frequency signal simulation method for three-dimensional scene target is proposed. This method divides scene map with 5*5m resolution and presets ackscattering-coefficient. According to

Multistatic SAR Imaging: Comparison of Simulation Results and Experimental Data [PDF]

, 2017
Synthetic aperture radar (SAR) systems in a multistatic configuration are a promising candidate for future Earth observation and reconnaissance radar systems. They overcome the sampling constraints inherent to single-channel SAR systems.
