2.3.1.9 Pulse Width Selection (only available in Master mode)

The pulse width toggle field allows selection of the desired transmitter pulse

width for the current range scale selected. If there is no pulse width toggle field,

this indicates that it is not available for the range currently being used.

Operator controls

Task

Selecting this toggle field allows the pulse length to

be switched e.g. from short pulse to medium pulse

and vice versa to optimize target discrimination with

respect to the selected range.

Use of a longer pulse improves target reception but, at the

same time, increases clutter returns.

When using longer pulses it may be difficult to differentiate

very close targets.

When a shorter pulse is used, reception of some weaker

targets will decrease, but clutter will also decrease,

resulting in better target detection.

The available pulse width selections for the Radar displays and the Radar

MTRs are illustrated in Table 2-7.
