Sector Select

This operator extracts a major or minor sector from a ping matrix, corresponding to the given tilt/bearing angle. The output variable data types are Multibeam angular position, Multibeam Sv, Multibeam TS or Multibeam unspecified dB, matched to whichever operand is used.

Operand 1

  • Matrix angular position
  • Matrix Sv
  • Matrix TS
  • Matrix unspecified dB

Settings

The Sector Select dialog box pages include (common) Variable Properties pages and these operator pages.

Sector Select

Sector Direction

Select the Minor-axis or Major-axis sector of the matrix data. The minor sector is a beam fan at a displayed bearing angle, which is the vertical slice of the matrix. The major sector is a beam fan at a displayed tilt angle which is a horizontal slice of the matrix.

Sector Selection

Select the Sector angle in degrees from the listed sectors. Angles are relative to the configuration in ping 0.

If a major sector is chosen, select a minor angle from Sector 0 (-45 °) to Sector 19 (0°). If a minor sector is chosen, select a major angle from Sector 0 (-30°) to Sector 24 (30°).
