New features have been added to SOPA:

• a square facet simulator using a cos^exp law to weight the effect of surfaces not facing the radar;
• the possibility to create maps of the estimated locations of the first returns for each frame;
• the possibility to create radargram-like images showing the minimum/maximum ground distance from the nadir point of the surface clutter contributions summing up in the simulations;
• plotting tools for quick visualization of all the main outputs of SOPA.

Have a look at the new features on the SOPA project page, and in particular on the new examples page!

The python3 open processing suite for SHARAD data SOPA now includes also the focuser SOFA!

Working with SHARAD data, starting from raw unfocused echoes to (squinted) processed radargrams is now only a few lines of code away.

Check it out on the SOPA project page.

By now, SOFA can focus only night time radargrams as no correction of ionosphere effects has been implemented yet... let me work on that ;)

Another project on radar sounder data: SOPA, which means SHARAD Open Focusing Attempt.
The idea behind SOPA is to create a common and simple python v3 API for reading, simulating and focusing available SHARAD data.
The development of SOPA is still ongoing. It already includes several interfaces for existing SHARAD data and a simple simulator. Check the details in the project dedicated page!

The International Journal of Remote Sensing published a paper I wrote about possible results and measurements obtained using SOFA.

The final paper is available at this link.

You can find the post-print version of the published paper here:

After a long time, a new project is online: SOFA! SOFA stands for SHARAD Open Focusing Attempt. This is an old code that I used to make some sofa-spare-time experiments on the SHAllow RADar (SHARAD) data acquired on Mars.
It allows focusing the raw radargrams using different squint angles and apertures. As shown in the Radargram enhancement and target physical slope estimation page, this processing makes it possible to visually enhance radargrams and obtain further physical information on subsurface targets.
As usual, a documentation and a download page are available!
I'm pretty sure that with this piece of code you will find water on Mars!
If so, let me know from the Contacts page!

I presented the development and deployment status of the street lighting monitoring solution I'm developing at work at the 2016 IEEE International Smart Cities Conference (ISC2)!

You can find the pre-print version of the published paper here:

A. Ferro, "Street lighting monitoring at cabinet level using open-source tools: A real scenario," 2016 IEEE International Smart Cities Conference (ISC2), Trento, 2016.
DOI: 10.1109/ISC2.2016.7580842

You can also download the final version of presentation here.

MOXA switches series EDS-405A/408A are nice and rugged devices, I'm using a lot of them at work. You can access them via telnet, but it's an interactive pseudo-graphic interface, you have to enter menus, move with arrows. Not a CLI like for Cisco switches.
Fortunately using the Linux utility "expect" plus knowing the right key codes, you can configure them in batch mode... for example you can batch change their network parameters using this script for changing the IP address of MOXA EDS-405A/408A switches via telnet.
Good luck!

I decided to open a new section on the website called Misc, that means "miscellaneous"... that means "everything and nothing".
I think I'll post there some scripts, instructions, or stuff like that.

For the moment there's one little script I'm using for changing the IP address of Cisco switches via telnet (in my case Cisco ME3400) with only one line and without the need to interactively login.
In the future, who knows? :)

See you!

A new project on AF-projects.it! I come back to Earth with SLightliMon, a Street Lighting lite Monitor.
This work is an evolution of an experiment started at work. An experiment that was so successfull, that now has become our main solution for the monitoring of street lighting power consumption, with almost 100 monitored power cabinets (still growing).
Here I publish the main core of the alarm detector. At work I developed also a basic web-based user interface, but here I want to publish a better one in the future.
In the meanwhile you may try the alarm detector.
Reading the documentation and having a look at the examples is mandatory before downloading and trying the code!
I also published a little document explaining how to set up a street lighting architecture based on free software.

As usual, have a look at the Contacts page if you want to write me!

Enjoy!

After some days of work, AF-projects.it is online and can be disclosed to The World! :)
As most of internet websites, The World won't care about this website, but ok... it will be enough if somebody will pass by here and may find something useful.

The first project hosted here is dSARsim, a "dummy" Synthetic Aperture Radar (SAR) simulator. Other projects will be posted and listed in the Projects page... soon or later :)

Don't hesitate to contact me if you have any question, suggestion or whatever. Just have a look at the page Contacts for that.

That's all!
Have a nice surfing :)
