Working with SDR receiver

Program for getting data from RTL-SDR receiver and plotting a spectrum graph from obtained data

Description

Initially this program was developed for the department of radiophysics of Kazan Federal University. RTL-SDR received waves from meteoradar reflected from meteor trails. I publish the program source code for educational purposes as an example of usage Soapy-SDR, gnuplot-iostream, fftw3 and argp libraries.

Usage

Without arguments program starts to collect iq-values from the RTL-SDR receiver. With the -p FILE_NAME.iq argument and program will plot the spectrum of saved signal. Use radar --usage for more info.

Building

You need to install SoapyRTLSDR and its dependencies and make sure you have all of the following packages before compiling:

• cmake
• g++ or clang compiler
• libfftw3-dev
• libgnuplot-iostream-dev

Clone this repo and run these commands:

$ mkdir build
$ cd build
$ cmake ..
$ cmake --build .
