Need MATLAB 2011a or above.
You will need a USRP or similar devices to record data in IQ format.
I - 16 Bits Q - 16 Bits
Dump 1090 is a Mode S decoder specifically for processing data offline.
The main features are:
- Single bit errors correction using the 24 bit CRC.
- Ability to decode positions and velocities of airplanes
- Decode raw IQ samples from file
Run the dump1090.m
Specify the parameters as follows:
seconds = 2;
dataPath = 'C:\USRP_DATA\ADSB';
filename = 'adsb_set_10MHz.dat';
sampRate = 1e7;
The sampRate depends on the sampling rate you are using for recording the raw IQ data.
You will get output like this:
-- We find a packet ...
-- Start index is 18385412 ...
-- DF type is 11 ...
-- Plane ID is 750257 ...
