Swath width calculator
Calculates total swath width on the seabed and minimum slant range for a given sonar altitude and swath angle. Results are theoretical and assume a flat seabed at constant depth.
θSwath angle (total) — input
ASonar altitude / nadir depth — input
BTotal swath width on seabed — output
CSlant range to outer beam — output
