Specifications

• 380x TDK Invensense T3902 PDM microphones.
• Artix-7 A100T FPGA.
• FT601Q parralel-to-usb bridge tested at up to 200MB/s.
• 32x 40khz Ultrasonic Piezoelectric emitters
• 2 free GPIOs

Capabilities

Active sonar

• Optimized for 40KHz operation.
• Up to 5°x5° beamwidth.
• Range up to 8 meters depending on target sonar cross-section.

Passive sonar

• Can detect a bike air chamber leak at 3 meters.

Software

The sonar comes with two demoes
- 2D Slicing camera, that shows the energyscape for a specific distance.
- 3D Camera, that shows the reflected energy with a 3d point cloud.

Both examples are made with C99 C, using Raylib and Sokol for real-time 2D/3D visualization.
