Abstract : A sonar system is disclosed which incorporates a first receiver for receiving an acoustical signal from a target via a vertical path sector of water encompassing said target, a second receiver for receiving an acoustical signal from said target via a horizontal path sector of water also encompassing said target, and readouts for displaying the images of said target along with the physical characteristics of said vertical and horizontal water path sectors encompassing it. Selector switches are employed that enable an operator to select any one of a number of said vertical and horizontal water path sectors and to highlight them if desired, so as to optimize the target image as a result of selecting the water path sectors having the least signal resistance. Optionally, the subject sonar may be made active by including a target search signal broadcasting means, so the aforementioned received acoustical signals will be target echo rather than target source signals.
