RadarBox24.com – Live Flight Tracker and Flight Status

AirNav Systems develops flight tracking software able to live track flights from around the globe. The solutions are developed by real aviation professionals (airline pilots, engineers and air traffic controllers) -and RadarBox24 was developed on a real world aviation environment. ADS-B receivers used are AirNav RadarBox Pro and AirNav RadarBox 3D. Every RadarBox receiver is designed to share real-time flight data to AirNav Systems servers. Data comes from thousands receivers from all over the world and is processed (at an amazing rate of over 20 million messages per day). Finally data is provided in web browsers and mobile solutions.

Now you can build your own Raspberry Pi data feeder using RBFeeder client and sent data to Radarbox24. This short article will explain everything you need to know about our new Linux based client and how you can install it on your Raspberry Pi.

Homemade 6 GHz FMCW radar

Henrik Forstén has a nice build log on his newest version of this homemade 6 GHz FMCW radar:

Frequency Modulated Continuous Wave (FMCW) radar works by transmitting a chirp which frequency changes linearly with time. This chirp is then radiated with the antenna, reflected from the target and is received by the receiving antenna. On the reception side the received signal that was delayed and undelayed copy of the transmitted chirp are mixed (multiplied) together.

122 GHz On-chip Radar

Silicon technology has made tremendous progress towards ever higher device cut-off frequencies. Nowadays all RF components for mm-Wave sensing applications up to 120 GHz can be realized.
Silicon Radar is a german company that designs and delivers Millimetre Wave Integrated Circuits (MMICs) on a technologically advanced level, manufactured in affordable Silicon-Germanium-Technology (SiGe). It has just introduced new development kits using GHz CMOS radar MMICs, which are built using SiGe or SiGe:C from IHP.

Silicon Radar participated in the European Commission 7th Framework Success project,  to develop ways to mass produce silicon mm-Wave SoCs at low cost – with STMicro, IHP, Evatronix, Selmic, Hightec, Bosch, the Karlsruhe Institute of Technology and the University of Toronto.

The development kits are:

assy_easyradarkit_270EasyRadar is for evaluating all of the firm’s TX/RX radar chips, and is “great for beginners and pros who want to start development and tweak system parameters”, said Silicon Radar.

EasyRadar features:

  • programmable FMCW parameters
  • signal processing
  • target recognition
  • web-based GUI
  • USB or wireless LAN communication with PC

The kit includes:

  • 122 GHz radar front end (see photo above)
  • 24 GHz radar front end (see lower photo)
  • controller board
  • baseband board with WiFi
  • lens for 122 GHz

You can download the user guide and the protocol description

simpleradar_270SimpleRadar is available to evaluate the firm’s 122 GHz radar front end.

It has the same functionality as the EasyRadar but is smaller (40 x 40mm), and can be used as a Wi-Fi-enabled radar sensor with integrated target recognition.

It has the following features:

  • programmable FMCW parameters
  • signal processing
  • target recognition
  • web-based GUI
  • USB communication with PC or over wireless LAN

You can check its user guide and the protocol description

“We offer high frequency circuits for radar solutions, phased-array-systems and wireless communications, for both custom specific ASIC design and supply of standard circuits in frequency range from 10GHz X-band up to 200GHz and above,” said the firm.

Possible applications using the kits are:

  • distance sensing applications such as industrial sensing (distance, speed, material characterisation),
  • public and private safety (motion detectors, even behind wall paper),
  • automotive (wheel suspension measurement, pedestrian safety),
  • replacement of cheap ultrasonic sensors (distance measurement)

Arduino Radar Tutorial: Fading an LED With My Breath

by build-electronic-circuits.com:

I built this Arduino radar project, where I control the brightness of an LED with my breath. In this tutorial, I will show you exactly how to do it.

It was an experiment to get the XeThru radar to work with Arduino. I plan to expand on this later, and build more useful applications.

And I will share with you how to connect the hardware, and how to create the Arduino code.
