Neither is better, they perform entirely different and often complementary functions.

Acoustic echoing (sonar) or satellite scanning methods.
One technology oceanographers use to explore the ocean floor is multibeam sonar. This advanced sonar system emits multiple sonar beams in a fan shape to create a detailed 3D map of the seafloor topography. Multibeam sonar helps scientists to accurately study the features and structures of the ocean floor.
Not quite sure, but scientists are discovering a newer, better Sonar, inspired by dolphins. Look it up, and see what you find. Maybe you could even come back here with a better answer than mine!
Satellite imagery is not typically used by ocean scientists to map the topography of the ocean floor, as it cannot penetrate the water to provide detailed depth information. Instead, methods such as multibeam sonar and lidar are commonly used to create detailed maps of the ocean floor.
Bearing resolution in sonar refers to the ability to distinguish between two closely spaced objects in terms of their direction relative to the sonar transducer. It depends on factors like the beamwidth, signal processing techniques, and the frequency of the sonar system. Higher bearing resolution allows for better target discrimination and localization.

Radar and sonar are both used for detecting objects, but they operate in different mediums. Radar uses radio waves to detect objects in the air or on the ground, while sonar uses sound waves to detect objects underwater. Radar is better for long-range detection and tracking of objects in the air, while sonar is better for underwater navigation and detecting objects beneath the surface of the water.
Remote sensing is the process of collecting data from a distance using satellite or aerial imagery, as well as sound waves like RADAR or SONAR. This technology allows us to gather information about the Earth's surface without physical contact. Remote sensing is widely used in various fields such as environmental monitoring, agriculture, and urban planning.
