RF is still RF, the only difference between what they’re shooting into the water to detect subs and what you’re shooting into your hot pockets is output power and frequency. It’s still radio detection and ranging, just at a frequency not typically used for it. Microwave frequencies are used for what one would consider to be typical radar applications, while extremely low frequency would be better suited for communications.
