The sound pulses are transmitted at various frequencies
depending on the application. Very high frequencies
(455 kHz) are used for greatest definition but the
operating depth is limited. High frequencies (200 kHz)
are commonly used on consumer sonar and provide a
good balance between depth performance and
resolution. Low frequencies (83 kHz) are typically used
to achieve greater depth capability.
The power output is the amount of energy generated
by the sonar transmitter. It is commonly measured
using two methods:
• Root Mean Square (RMS) measures power
output over the entire transmit cycle.
• Peak to Peak measures power output at the
highest points.
The benefits of increased power output are the
ability to detect smaller targets at greater distances,
ability to overcome noise, better high speed
performance and enhanced depth capability.
