A high-precision sonar experiment for commodity computer hardware.
- Generate an M-sequence
- Start an audio recording
- Play it over computer speakers
- Correlate against the known M-sequence to find when reflections were received.
Fairly well (in simulation)! As for the real world, well, this project aims to find out!
Polynomial abstraction, M-sequence generation, modulation/demodulation some aspects of audio all work.
- Clean up / verify audio TX/RX
- Command line interface
- More exhaustive testing
