a. Vertical resolution is the smallest distinguishable distance between the peaks of two reflections that can be
displayed on the screen as separate reflectors. Sound energy is reflected back to the sonar system when the
transmitted pulse encounters a change in density. The resolution of a sonar system is measured by its ability
to distinguish between two adjacent targets. The vertical resolution is dependent on the transmitted chirp
pulse bandwidth. It is theoretically calculated by the product of the transmitted pulse length (inverse of the
bandwidth) and half the speed of sound in water (approximately 750 m/s). For example, a full bandwidth pulse
from an SB-424 Tow Vehicle has a vertical resolution of 3.75 cm (1/20,000 x 750).
