2.9 Change transmission pulse width (SP/LP)
This radar provides a function capable of achieving suitable target detection by manually changing the
transmission pulse width.
Eight different pulse widths are available.

The short (narrow) pulse width used in short range has high resolution and is effective for dense
targets.
The long (wide) pulse width used in long range has high gain (sensitivity) and is effective for detecting
small targets.
Two different pulse widths are set by default in the following ranges, 0.75NM, 1.5NM, 3NM and 6NM.
Ranges 0.25NM and below, and 12NM and above are setup with same pulse width in SP and LP.
Note: Refer to 2.29 Pulse width to set pulse width.

1 Press SP/LP key. Two different pulse widths are toggled by each key press.
Current pulse width is shown at the upper left of the display.
Note: Pulse width can be changed directly at the upper left of the display, with cursor and ENT key.
