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.
Pulse width Pulse repetition frequency IF Band width
S1 0.08μs 2600Hz 15MHz
S2 0.15μs 2600Hz 15MHz
M1 0.3μs 2400Hz 15MHz
M2 0.4μs 2000Hz 3MHz
M3 0.6μs 1400Hz 3MHz
L1 0.8μs 1000Hz 3MHz
L2 1.2μs 600Hz 3MHz
L3 1.2μs 450Hz 3MHz
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 0.5NM 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.

* 32NM and 64NM is for 12kW only.
** 96NM is for 25kW only.
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.
