,
1. Introduction:
Used chiefly for hydrolocation in seas, rivers and lakes.
Using special technology, can work using one or two resonance frequencies.
Using wide-band technology, receiving sensitivity and transmitting response are very high.
Fine resolution of fore-and-aft clearance reduces blind zones Providing.
2. Application:
● locating
● Approach measurement
● escaped obstruction
● fish finder
