In this paper the experimental results of C-band synthetic aperture radar (SAR) system integration on an unmanned aerial vehicle (UAV) are shown. The goal of the presented trials was to check the capabilities and limitations of the SAR system in UAV applications. The trials were conducted with a UAV system developed and operated by the Portuguese Air Force Academy (PAFA) using a compact SAR system,...
In this paper the recent results of Synthetic Aperture Radar (SAR) experiments conducted at the Warsaw University of Technology are presented. In the experiments an SAR radar was mounted on a lightweight airborne platform. The main goal of this experiment was to verify the possibility of obtaining high quality SAR image using navigation data from a low-cost Inertial Navigation System (INS) and classical...
The paper presents new high resolution SAR results of real-life measurements using an updated ARS-400/ARS-800 SAR sensor installed on the maritime patrol aircraft M-28. The main role for such radars is surveying the sea surface, and the imaging of selected targets (e.g. ships, roads, vehicles, buildings, etc.) to help the operator in classifying them. In the present day increasing computing power,...
This paper presents a study on Synthetic Aperture Radar (SAR) based augmented Integrity Navigation Architecture (SARINA) system designing for UAV and missile platforms. The SARINA system is an advanced concept of air platform Inertial Navigation System, which takes an advantage of used SAR sensor for Earth imaging. The presents system created the 2D SAR and 3D InSAR images, which are respectively...
The paper presents digital beamforming for Passive Coherent Location (PCL) radar. The considered circular antenna array is a part of a passive system developed at Warsaw University of Technology. The system is based on FM radio transmitters. The array consists of eight half-wave dipoles arranged in a circular array covering 360deg with multiple beams. The digital beamforming procedure is presented,...
The paper present a concept of a simple MIMO (multiple input multiple output) PCL (passive coherent location) radar relying on FM radio transmitters of opportunity. The use of MIMO approach instead the classical phased antenna results in significant increase in surveillance volume without changing requirements for computational power.
