# Matlab Scripts for Evaluation of a TDOA System based on 3 RTL-SDRs ## Functionality: Matlab scripts according to my project on transmitter localization with time-difference-of-arrival (TDOA). [Presentation at the Software Defined Radio Academy, 2017](https://www.youtube.com/watch?v=Km4TU17b05s) Update 2019: All algorithm parameters including the positions of the receivers etc. can be specified in the configuration .m file The script is flexible and can be adapted to a 3-receiver scenario (with reference TX) anywhere. ### Input: Three recordings from (the three) receivers done with the librtlsdr-2freq (modified librtlsdr for 2 frequency operation). First frequency is the reference transmitter, second frequency is the measurement frequency (required length: 3.6e6 (i.e. 1.2e6 samples per frequency), 2 Msps sampling rate). ### Processing: * Delay analysis of reference signal to synchronize the receptions * Delay analysis of measurement signal to measure the TDOAs * Available Options: bandwidth filtering, correlation smoothing, correlation type switching, signal interpolation * Mulitlateration calculations for localization ### Output: A html/javascript file with a map showing the receivers, the hyperbolas and the most likely position of the transmitter.
