'Das Sonar' (the sonar device) usually refers to the device, whereas 'mit Sonar' (with sonar) or 'mithilfe von Sonar' (using sonar) often focuses on the method. The context therefore indicates whether the equipment or the method is being discussed.
Das Sonar des U-Boots zeigte einen unbekannten Kontakt an.
The submarine's sonar device indicated an unidentified contact.
Mit Sonar vermaßen die Forschenden die Tiefe des Fjords.
The researchers used sonar to measure the depth of the fjord.
When referring to the device, combinations with technical verbs are typical, such as 'das Sonar einschalten' (to switch on the sonar device), 'das Sonar einsetzen' (to use the sonar device), and 'das Sonar ortet ein Objekt' (the sonar device locates an object).
Die Besatzung setzte das Sonar ein, um ein Hindernis zu finden.
The crew used the sonar device to find an obstacle.
The sense referring to a method occurs mainly in technical, scientific, and maritime texts. In these contexts, 'Sonar' (sonar) often appears without an article after 'mit' (with) or 'mithilfe von' (using).
Das Team suchte mit Sonar nach Spuren auf dem Meeresboden.
