Powered by the impressive Google Earth Engine (GEE) platform, C-SAR Eye (link to the tool) tries to make Sentinel-1 satellites data analysis easier by focusing on changes in the captured C-SAR radar data. The tool allows users to customise a time frame for the data to be analysed and setup thresholds so to isolate changes […]
5GIT – Demo research
How to use it To illustrate some of the tool workings and in general suggest ways to use it in your researches, I’m going to guide you through a fast research over the Persian Gulf area, specifically we will check if as consequence of the August 17 and September 14 attacks on Saudi oil infrastructure, […]
SENTINEL-1 and the Seas of Japan
While checking for Patriot activity in South Korea I stumbled on the interesting increase of interferences in the seas surrounding Japan. This pushed me to investigate a little further to isolate the potential sources for them. HyÅ«ga class helicopter destroyers The vessels (2) which became operational in the late first decade of 2000 saw the […]
SENTINEL-1 and The Mediterranean Sea
A research into radar caused interferences over the Mediterranean Sea as revealed by SENTINEL-1 C-SAR data.
SENTINEL-1 C-SAR interference analysis. Intro
This article wants to be some kind of introduction to the technique first discovered and exposed by Harel Dan in his Medium post from 2018 (highly recommended read) which involves using the publicly available SENTINEL-1 satellites data to detect and locate powerful sources of radio frequencies in (some of) the C band. We will also […]
5Ghz Interference Tracker
5GIT is a tool developed in Google Earth Engine that uses SENTINEL-1 satellite data to isolate strong radio signal sources operating close to the 5.5 Ghz frequency on which the satellites CSAR sensors operate (CSAR stands for C band Synthetic Aperture Radar).
