sonar devices map the sea floor, radar just boils water unless the signal is balanced ungodly.
Yes, that is true. Scientists began using radar on moving ships to map large areas of the ocean floor in detail during the 1940s and 1950s. This method, known as swath mapping, allowed for more accurate and comprehensive mapping of the ocean floor compared to previous techniques.
RADAR was invented in England. That gave them an advatage in the air and on the coast. Eventually Germany had it but their radar system was not as good.
A special type of radar called sonar is used to detect objects underwater by emitting sound waves and detecting their reflections. Sonar is commonly used in applications such as navigation, communication with submarines, and mapping the ocean floor.

As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
1935
To locate underground utilities and sewer lines, you can use several methods, including utility mapping services, ground-penetrating radar (GPR), and electromagnetic locating devices. Utility mapping services can provide existing maps and records of underground infrastructure. GPR uses radar pulses to image the subsurface, while electromagnetic devices detect the electromagnetic fields generated by buried utilities. Additionally, contacting local utility companies for assistance and marking services is essential before any excavation work.
Radar was invented in 1935 by Scottish physicist Sir Robert Watson-Watt. He developed the first practical radar system for detecting aircraft.
Radar was first put on ships during WW2.
The newly invented radar.
airplane..bwahahahaha....
As best as we can tell its mountains and rifts, all mapping has been done by radar.
